Although immune checkpoint inhibitor (ICI) therapy has improved the prognosis of patients with metastatic UC with HV, the factors determining the prognosis of these patients following ICI therapy remains unclear. Methods The present, retrospective, multicentric study (YUSHIMA study-04) included patients with histologically confirmed mUC who received pembrolizumab as a second-line or later therapy between January 2018 and June 2023. The primary endpoint was the assessment of differences in prognostic factors of progression-free survival (PFS) and overall survival (OS) in patients with HV and those with pure UC (pUC). Results The study cohort consisted of 61 patients with HV and 331 with pUC. PFS and OS were comparable between the groups. The presence of lymph node metastasis (LNM) was independently associated with longer PFS (multivariate hazard ratio [mHR]: 0.35; P = 0.02) and OS (mHR: 0.25; P = 0.002) in the HV group but was not in the pUC group (univariate HR: 1.10; P = 0.54 and HR: 1.05; P = 0.76, respectively). When the prognosis of the groups was compared by LNM status, the HV group had significantly shorter PFS ( P = 0.003) and OS ( P = 0.008) in a subpopulation of patients without LNM. Conclusions The presence of LNM may be a HV-specific prognostic factor of a favorable outcome in patients with mUC receiving pembrolizumab as second-line or later therapy. Metastatic urothelial carcinoma histological variant pembrolizumab lymph node metastasis Figures Figure 1 Figure 2 Figure 3 INTRODUCTION Urothelial carcinoma (UC) harboring a histological variant (HV) accounts for up to 25% of cases of metastatic UC (mUC) [ 1 , 2 ] and is a particularly aggressive subset of UC which is generally associated with a prognosis that is poorer than that of pure UC (pUC) in patients receiving platinum-based chemotherapy [ 3 ]. The recent advent of immune checkpoint inhibitor (ICI) therapy as a form of second-line therapy administered after platinum-based chemotherapy has made the prognosis of HV comparable to that of pUC [ 4 – 6 ]. However, Given potentially different biological backgrounds between HV and pUC [ 7 – 9 ], ICI therapy may operate differently in HV. To date, however, no study has addressed this research question adequately. Using a multicentric mUC database (YUSHIMA Study-04), the present study assessed differences in factors determining the prognosis of mUC patients with HV and those with pUC receiving pembrolizumab. MATERIALS AND METHODS Study design and data collection The present, multicentric study retrospectively enrolled patients with histologically confirmed mUC who had received pembrolizumab after platinum-based chemotherapy between January 2018 and June 2023. The study protocol was approved by the Ethics Review Boards of the Institute of Science Tokyo School of Medicine and all referral hospitals (approval number: M2022-085). The primary endpoint was the assessment of differences in prognostic factors associated with progression-free survival (PFS) and overall survival (OS) in patients with HV and those with pUC. Clinical variables included age, sex, smoking history, synchronicity of metastasis, primary lesion, progression from non-muscle invasive bladder cancer, progression after BCG therapy, history of radical surgery for the primary lesion, neoadjuvant and adjuvant systemic chemotherapy, pembrolizumab treatment line, Eastern Cooperative Oncology Group-performance status (ECOG-PS), metastatic sites, and laboratory data, including hemoglobin, albumin, lactate dehydrogenase (LDH), and C-reactive protein (CRP). The neutrophil-to-lymphocyte ratio (NLR) and monocyte-to-lymphocyte ratio (MLR) were calculated by dividing the absolute neutrophil and monocyte counts by the lymphocyte count. The pathological diagnosis of individual cases was based on reports of regional pathologists. Treatment response was assessed using the Response Evaluation Criteria in Solid Tumors, version 1.1, which defines the objective response rate (ORR) and disease control rate (DCR) respectively as the proportion of patients with a partial or complete response and the proportion of patients with stable disease or a partial or complete response. Lymph node metastasis (LNM) status was classified as non-confined LNM and confined LNM, defined respectively as LNM with and without a metastasis at other organs or sites. Statistical analysis Fisher’s exact test and Wilcoxon rank-sum test was used to assess differences in categorical and continuous variables, respectively. PFS and OS were calculated from the date of pembrolizumab administration to the date of events or the last follow-up. Survival curves were drawn using the Kaplan-Meier method and compared using the log-rank test. The Cox proportional hazard model was used to assess variables associated with survival. To minimize the bias introduced by inappropriate regression adjustment for colliders rather than confounders, a directed acyclic graph (DAG) was generated to guide multivariate analysis [ 10 ]. A reduced multivariate model was developed using backward stepwise regression. All statistical analyses were performed using R (version 4.0.5) and EZR (version 1.54)[ 11 ]. Two-tailed P < 0.05 was considered to indicate statistical significance. RESULTS Baseline characteristics In total, 419 patients with mUC were enrolled; of these, 27 were excluded because they lacked a histological diagnosis, leaving 392 patients, including 61 with HV (16%) and 331 with pUC (84%, Table 1 ) for the final analysis. The 61 cases of HV consisted of 30, 16, 5, 5, 3, 1, and 1 case of the squamous, glandular, micropapillary, sarcomatoid, plasmacytoid, nested, and giant cell variant, respectively (Table 2 ). The median age was 74 years, and 288 (73%) patients were male. The primary lesions occurred in the bladder, renal pelvis, and ureter in 208 (53%), 73 (19%), and 101 (26%) patients, respectively. Radical surgery was performed for 206 (53%) patients, of whom 117 (30%) and 57 (15%) received platinum-based neoadjuvant chemotherapy and adjuvant chemotherapy, respectively. Pembrolizumab was administered to 30 (8%) patients as the first-line treatment for mUC within a year after neoadjuvant or adjuvant chemotherapy administration. Among the remaining 362 (92%) patients receiving first-line, platinum-based chemotherapy, switch- maintenance avelumab was given to 13 (3%) patients before pembrolizumab administration. LNM and a visceral or bone metastasis were present in 284 (72%) and 239 (61%) patients, respectively, at the time of pembrolizumab administration. Enfortumab vedotin was administered to 83 (21%) patients after disease progression occurred during pembrolizumab therapy. The prevalence of progression from NMIBC and NLR was significantly higher in the HV group than in the pUC group (21% vs. 11%; P = 0.03; and 4.34 vs. 3.75; P = 0.04, respectively. Table 1 ).

Figure 1 shows that the ORR (38% vs. 28%; P = 0.06), DCR (60% vs. 45%; P = 0.08), PFS (univariate hazard ratio [HR] of HV: 0.85; P = 0.40), and OS (univariate HR of HV: 1.04; P = 0.83) did not differ significantly between the groups. Next, factors determining the prognosis were evaluated separately for the HV and pUC groups. In the former group, PFS and OS-related events were observed in 32 and 41 patients, respectively, during the follow-up period (median: 8.1 months; interquartile range [IQR]: 3.2–19.7 months). The median time to progression and death was 3.4 and 6.3 months, respectively. As shown in Table 3 , the presence of LNM was independently associated with PFS (HR: 0.35; P = 0.02) along with liver metastasis (HR: 3.55; P = 0.03) and albumin (HR: 0.36 for 1 g/dL increase; P = 0.006). The presence of LNM was also independently associated with OS (HR: 0.25; P = 0.002) along with liver metastasis (HR: 3.23; P = 0.01), albumin (HR: 0.31 for 1 g/dL increase; P = 0.002), and ECOG-PS (HR: 2.42 for ≥ 1 vs. 0; P = 0.02).

The median time to progression and death was 3.8 and 8.7 months, respectively. Smoking history (HR: 1.65; P = 0.001), ECOG-PS (HR: 2.14 for ≥ 1 vs. 0; P < 0.001), albumin (HR: 0.52 for 1 g/dL increase; P < 0.001), and LDH (HR: 1.00 for 1 IU/L increase; P < 0.001) were independently associated with PFS (Table 3 ). ECOG-PS (HR: 1.95 for ≥ 1 vs. 0; P < 0.001) and albumin (HR: 0.45 for 1 g/dL increase; P < 0.001) were independently associated with OS. LNM was a predictor of a favorable prognosis of HV but not pUC In the entire cohort, LNM was not significantly associated with PFS (HR: 0.96; P = 0.76) or OS (HR: 0.95; P = 0.72). Figure 2 shows the outcomes of pembrolizumab therapy by LNM status (confined LNM, non-confined LNM, and no LNM) in the HV and pUC groups. In the former group, the DCR was significantly lower in patients without LNM (18% vs. 65%, P = 0.005; Fig. 2 A and Supplementary Fig. 1A). PFS and OS curves were clearly diverged by LNM status, indicating a statistically significant difference ( P = 0.004 for both; Figs. 2 B and 2 C). The prognosis improved in the descending order of confined LNM, non-confined LNM, and no LNM. In the pUC group, the DCR was significantly lower in patients with non-confined LNM than in those with confined LNM or those with no LNM (37% vs. 51% vs. 53%; P = 0.02; Fig. 2 D). The PFS and OS curves less clearly diverged by LNM status than those of the HV group, but the difference was still statistically significant; unlike in the HV group, non-confined LNM was associated with shorter PFS and OS than no LNM (Figs. 2 E and 2 F). When survival curves were drawn only by the presence or absence of LNM, PFS and OS were significantly longer in patients with LNM than those with no LNM in the HV group ( P = 0.004 and 0.01, respectively) but were equivalent in the pUC group (Supplementary Fig. 1). Sensitivity analysis was conducted to verify whether pembrolizumab therapy had a favorable impact on the prognosis of LNM in patients with HV. The distribution of the HV subtypes did not differ significantly by the presence or absence of LNM (Table 2 ). The former was associated with a lower frequency of neoadjuvant chemotherapy ( P = 0.02), a higher incidence of synchronous metastasis ( P = 0.08), and lower frequency of previous radical surgery ( P = 0.09) ( P < 0.10 in the HV group; Table 4 ). As these variables had the potential to confound the causality between LNM and the prognosis following pembrolizumab therapy, a DAG consisting of these variables was constructed (Supplementary Fig. 2) to guide multivariate analysis, which found the presence of LNM to be significantly associated with improved PFS (HR: 0.25; P = 0.008) and OS (HR: 0.30; P = 0.009; Supplementary Table 1). Furthermore, a comparison of the prognosis by the presence or absence of LNM in subgroups stratified by independent, prognostic factors (liver metastasis, albumin, and ECOG-PS) in the HV group found that patients with LNM had longer PFS and OS than those without LNM across all the subgroups (Supplementary Fig. 3). These findings indicated that the presence of LNM was an independent predictor of a favorable prognosis in patients with HV receiving pembrolizumab.

In the confined LNM subgroup, neither the ORR nor the DCR differed significantly between the groups (Fig. 3 A). PFS and OS were longer in the HV group ( P = 0.16 vs. 0.20; Figs. 3 B and 3 C). In the non-confined LNM subgroup, HV had a significantly better ORR (46% vs. 24%; P = 0.02) and DCR (63% vs. 37%; P = 0.001) (Fig. 3 D). However, PFS and OS were comparable in the two groups (Figs. 3 E and 3 F). In the no LNM subgroup, HV had a poorer DCR (22% vs. 51%; P = 0.05; Fig. 3 G) and significantly shorter PFS and OS ( P = 0.003 and 0.008, respectively; Figs. 3 H and 3 I). Taken together, the outcomes of pembrolizumab therapy in the HV group were dismal in the absence of LNM whereas they were comparable or even better than those in the pUC group in the presence of LNM. DISCUSSION The present study demonstrated that the presence of LNM was significantly and independently associated with a favorable prognosis in patients with HV receiving pembrolizumab therapy for mUC. Importantly, the prognostic advantage of LNM was not observed in patients with pUC. Unlike in the pUC group, in the HV group the presence of LNM was significantly associated with a better DCR and longer PFS and OS. Notably, only in the HV group the PFS and OS curves were clearly stratified in a stepwise manner by LNM status, and patients with no LNM had a much poorer prognosis than their counterparts. The present study is the first to demonstrate that LNM may be an HV-specific factor of a favorable prognosis in patients with mUC receiving ICI therapy. Although the prognostic impact of LNM has been investigated in several studies, the topic remains controversial where patients with HV receiving ICI therapy are concerned [ 12 – 14 ]. A previous, retrospective, multicentric study demonstrated that confined LNM was associated with a better outcome in patients with mUC receiving either first- or second-line ICI therapy [ 12 ]. A meta-analysis of randomized controlled trials found atezolizumab to be associated with better OS than chemotherapy in patients with LNM receiving second-line treatment [ 13 ]. However, another study reported that LNM was an independent factor of an unfavorable prognosis in patients with mUC receiving pembrolizumab or chemotherapy as second-line treatment [ 14 ]. Based on the findings of the present study, it may be hypothesized that the presence of LNM creates a tumor immune microenvironment which is more conducive to eliciting a response to pembrolizumab therapy in HV than in pUC. In fact, the ORR and DCR were significantly higher in patients with LNM in the HV group than in the pUC group (47% vs. 29%; P = 0.02; and 68% vs. 42%; P = 0.002; data not shown). Lymph nodes play an important role in priming and activating anti-tumor immunity [ 15 ] by facilitating the presentation of tumor antigens to immune cells, thereby allowing a more robust, anti-tumor immune response, particularly to tumors with high immunogenicity. Among the HVs, the tumor mutational burden is higher in the micropapillary, plasmacytoid, and neuroendocrine variants than in pUC but is lower in the squamous, glandular, sarcomatoid, and nested variants [ 9 ]. Since the latter group of HVs comprised up to 90% of the HV cases with LNM in the present study, the higher immunogenicity of LNM was unlikely to have been a factor in our findings. While the mechanism underlying the HV-specific impact of LNM on the prognosis is still unclear, our findings support the hypothesis that the tumor immune microenvironment associated with LNM elicits stronger anti-tumor immunity in HV than in pUC, thereby conducing to the favorable effects of PD-1 inhibition. Notably, the prognosis was significantly poorer in the HV group in the absence of LNM. Most of the patients in the present study had a visceral or bone metastasis. Their dismal prognosis after pembrolizumab therapy may be attributable to a more strongly immunosuppressive tumor microenvironment in visceral and bone metastases [ 16 , 17 ] and greater aggressiveness associated with HVs [ 9 , 18 ]. A number of retrospective studies [ 4 – 6 ] and a post-hoc analysis of KEYNOTE-045 trial [ 19 ] demonstrated comparable outcomes in patients with HV and those with pUC receiving pembrolizumab, a finding corroborated by the present study. Basal-type HVs, such as the squamous, sarcomatoid, and nested variants, [ 20 ] are characterized by higher PD-L1 expression and more abundant, cytotoxic T lymphocyte (CTL) infiltrates [ 8 ], which can enhance the therapeutic effect of PD-1 blockade. The glandular, micropapillary, and plasmacytoid variants frequently display mutations of the telomerase reverse transcriptase promoter regions [ 21 – 23 ] that are linked to favorable outcomes of ICI therapy [ 24 ]. These molecular characteristics might contribute to producing comparable outcomes of pembrolizumab therapy in the HV and pUC groups although in general, HV is clinically more aggressive than pUC. The present study has several limitations. First, it may have included biases typically associated with retrospective and multicentric studies enrolling a relatively small sample population. Second, the histological typing was not performed by central pathologists in the study but relied on past pathology reports. Third, the extent of the HVs was not considered; a higher proportion of some HVs, such as the micropapillary variant, appeared to be associated with a poor prognosis in the absence of a metastasis [ 25 ]. However, given the heterogeneity of tumor morphology in the primary lesion and metastases [ 26 , 27 ], pathologically evaluating the full range HVs in all the HV cases may not be important. Despite these limitations, this study was the first to demonstrate that LNM may be a HV-specific factor determining the prognosis of patients with HV receiving pembrolizumab therapy. Further studies enrolling a larger cohort and incorporating a central pathological review are warranted to verify the present findings. CONCLUSIONS LNM may be a HV-specific factor determining the prognosis of patients with mUC receiving pembrolizumab as second-line or later treatment.

Clinical variables included age, sex, smoking history, synchronicity of metastasis, primary lesion, progression from non-muscle invasive bladder cancer, progression after BCG therapy, history of radical surgery for the primary lesion, neoadjuvant and adjuvant systemic chemotherapy, pembrolizumab treatment line, Eastern Cooperative Oncology Group-performance status (ECOG-PS), metastatic sites, and laboratory data, including hemoglobin, albumin, lactate dehydrogenase (LDH), and C-reactive protein (CRP). The neutrophil-to-lymphocyte ratio (NLR) and monocyte-to-lymphocyte ratio (MLR) were calculated by dividing the absolute neutrophil and monocyte counts by the lymphocyte count. The pathological diagnosis of individual cases was based on reports of regional pathologists. Treatment response was assessed using the Response Evaluation Criteria in Solid Tumors, version 1.1, which defines the objective response rate (ORR) and disease control rate (DCR) respectively as the proportion of patients with a partial or complete response and the proportion of patients with stable disease or a partial or complete response. Lymph node metastasis (LNM) status was classified as non-confined LNM and confined LNM, defined respectively as LNM with and without a metastasis at other organs or sites.\u003c/p\u003e\u003c/div\u003e\u003cdiv id=\"Sec4\" class=\"Section2\"\u003e\u003ch2\u003eStatistical analysis\u003c/h2\u003e\u003cp\u003eFisher\u0026rsquo;s exact test and Wilcoxon rank-sum test was used to assess differences in categorical and continuous variables, respectively.

In the former group, the DCR was significantly lower in patients without LNM (18% vs. 65%, \u003cem\u003eP\u003c/em\u003e\u0026thinsp;=\u0026thinsp;0.005; Fig.\u0026nbsp;\u003cspan refid=\"Fig2\" class=\"InternalRef\"\u003e2\u003c/span\u003eA and Supplementary Fig.\u0026nbsp;1A). PFS and OS curves were clearly diverged by LNM status, indicating a statistically significant difference (\u003cem\u003eP\u003c/em\u003e\u0026thinsp;=\u0026thinsp;0.004 for both; Figs.\u0026nbsp;\u003cspan refid=\"Fig2\" class=\"InternalRef\"\u003e2\u003c/span\u003eB and \u003cspan refid=\"Fig2\" class=\"InternalRef\"\u003e2\u003c/span\u003eC). The prognosis improved in the descending order of confined LNM, non-confined LNM, and no LNM. In the pUC group, the DCR was significantly lower in patients with non-confined LNM than in those with confined LNM or those with no LNM (37% vs. 51% vs. 53%; \u003cem\u003eP\u003c/em\u003e\u0026thinsp;=\u0026thinsp;0.02; Fig.\u0026nbsp;\u003cspan refid=\"Fig2\" class=\"InternalRef\"\u003e2\u003c/span\u003eD). The PFS and OS curves less clearly diverged by LNM status than those of the HV group, but the difference was still statistically significant; unlike in the HV group, non-confined LNM was associated with shorter PFS and OS than no LNM (Figs.\u0026nbsp;\u003cspan refid=\"Fig2\" class=\"InternalRef\"\u003e2\u003c/span\u003eE and \u003cspan refid=\"Fig2\" class=\"InternalRef\"\u003e2\u003c/span\u003eF). When survival curves were drawn only by the presence or absence of LNM, PFS and OS were significantly longer in patients with LNM than those with no LNM in the HV group (\u003cem\u003eP\u003c/em\u003e\u0026thinsp;=\u0026thinsp;0.004 and 0.01, respectively) but were equivalent in the pUC group (Supplementary Fig.\u0026nbsp;1).\u003c/p\u003e\u003cp\u003e\u003c/p\u003e\u003cp\u003eSensitivity analysis was conducted to verify whether pembrolizumab therapy had a favorable impact on the prognosis of LNM in patients with HV. The distribution of the HV subtypes did not differ significantly by the presence or absence of LNM (Table\u0026nbsp;\u003cspan refid=\"Tab2\" class=\"InternalRef\"\u003e2\u003c/span\u003e). The former was associated with a lower frequency of neoadjuvant chemotherapy (\u003cem\u003eP\u003c/em\u003e\u0026thinsp;=\u0026thinsp;0.02), a higher incidence of synchronous metastasis (\u003cem\u003eP\u003c/em\u003e\u0026thinsp;=\u0026thinsp;0.08), and lower frequency of previous radical surgery (\u003cem\u003eP\u003c/em\u003e\u0026thinsp;=\u0026thinsp;0.09) (\u003cem\u003eP\u003c/em\u003e\u0026thinsp;\u0026lt;\u0026thinsp;0.10 in the HV group; Table\u0026nbsp;\u003cspan refid=\"Tab4\" class=\"InternalRef\"\u003e4\u003c/span\u003e). As these variables had the potential to confound the causality between LNM and the prognosis following pembrolizumab therapy, a DAG consisting of these variables was constructed (Supplementary Fig.\u0026nbsp;2) to guide multivariate analysis, which found the presence of LNM to be significantly associated with improved PFS (HR: 0.25; \u003cem\u003eP\u003c/em\u003e\u0026thinsp;=\u0026thinsp;0.008) and OS (HR: 0.30; \u003cem\u003eP\u003c/em\u003e\u0026thinsp;=\u0026thinsp;0.009; Supplementary Table\u0026nbsp;1). Furthermore, a comparison of the prognosis by the presence or absence of LNM in subgroups stratified by independent, prognostic factors (liver metastasis, albumin, and ECOG-PS) in the HV group found that patients with LNM had longer PFS and OS than those without LNM across all the subgroups (Supplementary Fig.\u0026nbsp;3). These findings indicated that the presence of LNM was an independent predictor of a favorable prognosis in patients with HV receiving pembrolizumab.\u003c/p\u003e\u003cp\u003e\u003cdiv

Taken together, the outcomes of pembrolizumab therapy in the HV group were dismal in the absence of LNM whereas they were comparable or even better than those in the pUC group in the presence of LNM.\u003c/p\u003e\u003cp\u003e\u003c/p\u003e"},{"header":"DISCUSSION","content":"\u003cp\u003eThe present study demonstrated that the presence of LNM was significantly and independently associated with a favorable prognosis in patients with HV receiving pembrolizumab therapy for mUC. Importantly, the prognostic advantage of LNM was not observed in patients with pUC. Unlike in the pUC group, in the HV group the presence of LNM was significantly associated with a better DCR and longer PFS and OS. Notably, only in the HV group the PFS and OS curves were clearly stratified in a stepwise manner by LNM status, and patients with no LNM had a much poorer prognosis than their counterparts. The present study is the first to demonstrate that LNM may be an HV-specific factor of a favorable prognosis in patients with mUC receiving ICI therapy.\u003c/p\u003e\u003cp\u003eAlthough the prognostic impact of LNM has been investigated in several studies, the topic remains controversial where patients with HV receiving ICI therapy are concerned [\u003cspan additionalcitationids=\"CR13\" citationid=\"CR12\" class=\"CitationRef\"\u003e12\u003c/span\u003e\u0026ndash;\u003cspan citationid=\"CR14\" class=\"CitationRef\"\u003e14\u003c/span\u003e]. A previous, retrospective, multicentric study demonstrated that confined LNM was associated with a better outcome in patients with mUC receiving either first- or second-line ICI therapy [\u003cspan citationid=\"CR12\" class=\"CitationRef\"\u003e12\u003c/span\u003e]. A meta-analysis of randomized controlled trials found atezolizumab to be associated with better OS than chemotherapy in patients with LNM receiving second-line treatment [\u003cspan citationid=\"CR13\" class=\"CitationRef\"\u003e13\u003c/span\u003e]. However, another study reported that LNM was an independent factor of an unfavorable prognosis in patients with mUC receiving pembrolizumab or chemotherapy as second-line treatment [\u003cspan citationid=\"CR14\" class=\"CitationRef\"\u003e14\u003c/span\u003e]. Based on the findings of the present study, it may be hypothesized that the presence of LNM creates a tumor immune microenvironment which is more conducive to eliciting a response to pembrolizumab therapy in HV than in pUC. In fact, the ORR and DCR were significantly higher in patients with LNM in the HV group than in the pUC group (47% vs. 29%; \u003cem\u003eP\u003c/em\u003e\u0026thinsp;=\u0026thinsp;0.02; and 68% vs. 42%; \u003cem\u003eP\u003c/em\u003e\u0026thinsp;=\u0026thinsp;0.002; data not shown). Lymph nodes play an important role in priming and activating anti-tumor immunity [\u003cspan citationid=\"CR15\" class=\"CitationRef\"\u003e15\u003c/span\u003e] by facilitating the presentation of tumor antigens to immune cells, thereby allowing a more robust, anti-tumor immune response, particularly to tumors with high immunogenicity. Among the HVs, the tumor mutational burden is higher in the micropapillary, plasmacytoid, and neuroendocrine variants than in pUC but is lower in the squamous, glandular, sarcomatoid, and nested variants [\u003cspan citationid=\"CR9\" class=\"CitationRef\"\u003e9\u003c/span\u003e]. Since the latter group of HVs comprised up to 90% of the HV cases with LNM in the present study, the higher immunogenicity of LNM was unlikely to have been a factor in our findings. While the mechanism underlying the HV-specific impact of LNM on the prognosis is still unclear, our findings support the hypothesis that the tumor immune microenvironment associated with LNM elicits stronger anti-tumor immunity in HV than in pUC, thereby conducing to the favorable effects of PD-1 inhibition.\u003c/p\u003e\u003cp\u003eNotably, the prognosis was significantly poorer in the HV group in the absence of LNM. Most of the patients in the present study had a visceral or bone metastasis. Their dismal prognosis after pembrolizumab therapy may be attributable to a more strongly immunosuppressive tumor microenvironment in visceral and bone metastases [\u003cspan citationid=\"CR16\" class=\"CitationRef\"\u003e16\u003c/span\u003e, \u003cspan citationid=\"CR17\" class=\"CitationRef\"\u003e17\u003c/span\u003e] and greater aggressiveness associated with HVs [\u003cspan citationid=\"CR9\" class=\"CitationRef\"\u003e9\u003c/span\u003e, \u003cspan citationid=\"CR18\" class=\"CitationRef\"\u003e18\u003c/span\u003e].\u003c/p\u003e\u003cp\u003eA number of retrospective studies [\u003cspan additionalcitationids=\"CR5\" citationid=\"CR4\" class=\"CitationRef\"\u003e4\u003c/span\u003e\u0026ndash;\u003cspan citationid=\"CR6\" class=\"CitationRef\"\u003e6\u003c/span\u003e] and a post-hoc analysis of KEYNOTE-045 trial [\u003cspan citationid=\"CR19\" class=\"CitationRef\"\u003e19\u003c/span\u003e] demonstrated comparable outcomes in patients with HV and those with pUC receiving pembrolizumab, a finding corroborated by the present study. Basal-type HVs, such as the squamous, sarcomatoid, and nested variants, [\u003cspan citationid=\"CR20\" class=\"CitationRef\"\u003e20\u003c/span\u003e] are characterized by higher PD-L1 expression and more abundant, cytotoxic T lymphocyte (CTL) infiltrates [\u003cspan citationid=\"CR8\" class=\"CitationRef\"\u003e8\u003c/span\u003e], which can enhance the therapeutic effect of PD-1 blockade. The glandular, micropapillary, and plasmacytoid variants frequently display mutations of the telomerase reverse transcriptase promoter regions [\u003cspan additionalcitationids=\"CR22\" citationid=\"CR21\" class=\"CitationRef\"\u003e21\u003c/span\u003e\u0026ndash;\u003cspan citationid=\"CR23\" class=\"CitationRef\"\u003e23\u003c/span\u003e] that are linked to favorable outcomes of ICI therapy [\u003cspan citationid=\"CR24\" class=\"CitationRef\"\u003e24\u003c/span\u003e]. These molecular characteristics might contribute to producing comparable outcomes of pembrolizumab therapy in the HV and pUC groups although in general, HV is clinically more aggressive than pUC.\u003c/p\u003e\u003cp\u003eThe present study has several limitations. First, it may have included biases typically associated with retrospective and multicentric studies enrolling a relatively small sample population. Second, the histological typing was not performed by central pathologists in the study but relied on past pathology reports. Third, the extent of the HVs was not considered; a higher proportion of some HVs, such as the micropapillary variant, appeared to be associated with a poor prognosis in the absence of a metastasis [\u003cspan citationid=\"CR25\" class=\"CitationRef\"\u003e25\u003c/span\u003e]. However, given the heterogeneity of tumor morphology in the primary lesion and metastases [\u003cspan citationid=\"CR26\" class=\"CitationRef\"\u003e26\u003c/span\u003e, \u003cspan citationid=\"CR27\" class=\"CitationRef\"\u003e27\u003c/span\u003e], pathologically evaluating the full range HVs in all the HV cases may not be important. Despite these limitations, this study was the first to demonstrate that LNM may be a HV-specific factor determining the prognosis of patients with HV receiving pembrolizumab therapy. Further studies enrolling a larger cohort and incorporating a central pathological review are warranted to verify the present findings.\u003c/p\u003e"},{"header":"CONCLUSIONS","content":"\u003cp\u003eLNM may be a HV-specific factor determining the prognosis of patients with mUC receiving pembrolizumab as second-line or later treatment.\u003c/p\u003e"},{"header":"Abbreviations","content":"\u003cdiv class=\"DefinitionList\"\u003e\u003cdiv class=\"DefinitionListEntry\"\u003e\u003cdiv class=\"Term\"\u003eCR\u003c/div\u003e\u003cdiv class=\"Description\"\u003e\u003cp\u003ecomplete response\u003c/p\u003e\u003c/div\u003e\u003c/div\u003e\u003cdiv class=\"DefinitionListEntry\"\u003e\u003cdiv class=\"Term\"\u003eHV\u003c/div\u003e\u003cdiv class=\"Description\"\u003e\u003cp\u003emetastatic urothelial cancer with a histological variant\u003c/p\u003e\u003c/div\u003e\u003c/div\u003e\u003cdiv class=\"DefinitionListEntry\"\u003e\u003cdiv class=\"Term\"\u003eORR\u003c/div\u003e\u003cdiv class=\"Description\"\u003e\u003cp\u003eobjective response rate\u003c/p\u003e\u003c/div\u003e\u003c/div\u003e\u003cdiv class=\"DefinitionListEntry\"\u003e\u003cdiv class=\"Term\"\u003eDCR\u003c/div\u003e\u003cdiv class=\"Description\"\u003e\u003cp\u003edisease control rate\u003c/p\u003e\u003c/div\u003e\u003c/div\u003e\u003cdiv class=\"DefinitionListEntry\"\u003e\u003cdiv class=\"Term\"\u003epUC\u003c/div\u003e\u003cdiv class=\"Description\"\u003e\u003cp\u003epure urothelial cancer\u003c/p\u003e\u003c/div\u003e\u003c/div\u003e\u003cdiv class=\"DefinitionListEntry\"\u003e\u003cdiv class=\"Term\"\u003ePFS\u003c/div\u003e\u003cdiv class=\"Description\"\u003e\u003cp\u003eprogression-free survival\u003c/p\u003e\u003c/div\u003e\u003c/div\u003e\u003cdiv class=\"DefinitionListEntry\"\u003e\u003cdiv class=\"Term\"\u003ePR\u003c/div\u003e\u003cdiv class=\"Description\"\u003e\u003cp\u003epartial response\u003c/p\u003e\u003c/div\u003e\u003c/div\u003e\u003cdiv class=\"DefinitionListEntry\"\u003e\u003cdiv class=\"Term\"\u003eOS\u003c/div\u003e\u003cdiv class=\"Description\"\u003e\u003cp\u003eoverall survival\u003c/p\u003e\u003c/div\u003e\u003c/div\u003e\u003cdiv class=\"DefinitionListEntry\"\u003e\u003cdiv class=\"Term\"\u003eSD\u003c/div\u003e\u003cdiv class=\"Description\"\u003e\u003cp\u003estable disease\u003c/p\u003e\u003c/div\u003e\u003c/div\u003e\u003cdiv class=\"DefinitionListEntry\"\u003e\u003cdiv class=\"Term\"\u003ePD\u003c/div\u003e\u003cdiv class=\"Description\"\u003e\u003cp\u003eprogressive disease\u003c/p\u003e\u003c/div\u003e\u003c/div\u003e\u003cdiv class=\"DefinitionListEntry\"\u003e\u003cdiv class=\"Term\"\u003eNE\u003c/div\u003e\u003cdiv class=\"Description\"\u003e\u003cp\u003enot evaluable\u003c/p\u003e\u003c/div\u003e\u003c/div\u003e\u003c/div\u003e"},{"header":"Declarations","content":"\u003cp\u003e\u003cstrong\u003eConflict of Interest:\u003c/strong\u003e\u003cp\u003eThe authors declare no competing interests.\u003c/p\u003e\u003c/p\u003e\u003cp\u003e\u003cb\u003eEthical Approval statement\u003c/b\u003e: Science Tokyo School of Medicine and all referral hospitals (approval number: M2022-085).\u003c/p\u003e\u003c/p\u003e\u003cp\u003e\u003cstrong\u003eInformed Consent:\u003c/strong\u003e\u003cp\u003eThe requirement for informed consent was waived by the institutional review board.\u003c/p\u003e\u003c/p\u003e\u003ch2\u003eFunding Source:\u003c/h2\u003e\u003cp\u003eNone\u003c/p\u003e\u003ch2\u003eAuthors\u0026rsquo; contributions:\u003c/h2\u003e\u003cp\u003e\u003cb\u003eIchiro Yonese\u003c/b\u003e: Conceptualization, Data curation, Investigation, Writing \u0026ndash; original draft. \u003cb\u003eFumitaka Koga\u003c/b\u003e: Supervision, Writing \u0026ndash; review and editing. \u003cb\u003eMasahiro Toide\u003c/b\u003e: Data curation. \u003cb\u003eYuya Maezawa\u003c/b\u003e: Data curation. \u003cb\u003eKensaku Ishihara\u003c/b\u003e: Data curation. \u003cb\u003eNaoki Inoue\u003c/b\u003e: Data curation. \u003cb\u003eKenji Tanabe\u003c/b\u003e: Data curation. \u003cb\u003eKeita Izumi\u003c/b\u003e: Data curation. \u003cb\u003eMotohiro Fujiwara\u003c/b\u003e: Data curation. \u003cb\u003eTakanobu Yamamoto\u003c/b\u003e: Data curation. \u003cb\u003eSho Uehara\u003c/b\u003e: Data curation. \u003cb\u003eSaori Araki\u003c/b\u003e: Data curation. \u003cb\u003eMasaharu Inoue\u003c/b\u003e: Data curation. \u003cb\u003eRyoji Takazawa\u003c/b\u003e: Data curation. \u003cb\u003eNoboru Numao\u003c/b\u003e: Data curation. \u003cb\u003eYukihiro Ohtsuka\u003c/b\u003e: Data curation. \u003cb\u003eHajime Tanaka\u003c/b\u003e: Supervision. \u003cb\u003eSoichiro Yoshida\u003c/b\u003e: Supervision. \u003cb\u003eYasuhisa Fujii\u003c/b\u003e: Supervision.\u003c/p\u003e\u003ch2\u003eData Availability:\u003c/h2\u003e\u003cp\u003eThe datasets are available upon reasonable request.

PFS and OS were comparable between the groups. The presence of lymph node metastasis (LNM) was independently associated with longer PFS (multivariate hazard ratio [mHR]: 0.35; \u003cem\u003eP\u003c/em\u003e = 0.02) and OS (mHR: 0.25; \u003cem\u003eP\u003c/em\u003e = 0.002) in the HV group but was not in the pUC group (univariate HR: 1.10; \u003cem\u003eP\u003c/em\u003e = 0.54 and HR: 1.05; \u003cem\u003eP\u003c/em\u003e = 0.76, respectively). When the prognosis of the groups was compared by LNM status, the HV group had significantly shorter PFS (\u003cem\u003eP\u003c/em\u003e = 0.003) and OS (\u003cem\u003eP\u003c/em\u003e = 0.008) in a subpopulation of patients without LNM.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eConclusions\u003c/strong\u003e\u003c/p\u003e\n\u003cp\u003eThe presence of LNM may be a HV-specific prognostic factor of a favorable outcome in patients with mUC receiving pembrolizumab as second-line or later therapy.\u003c/p\u003e","manuscriptTitle":"Histological variant-specific significance of lymph node metastasis for the prognosis of metastatic urothelial carcinoma treated with pembrolizumab: A retrospective multicentric study (YUSHIMA study-04)","msid":"","msnumber":"","nonDraftVersions":[{"code":1,"date":"2025-09-30 16:37:13","doi":"10.21203/rs.3.rs-7630865/v1","editorialEvents":[{"type":"communityComments","content":0}],"status":"published","journal":{"display":true,"email":"
