Abstract
CONTEXT Lymph node (LN) involvement in penile cancer is associated with poor survival. Early diagnosis and management significantly impact survival, with multimodal treatment approaches often considered in advanced disease. OBJECTIVE To assess the clinical effectiveness of treatment options available for the management of inguinal and pelvic lymphadenopathy in men with penile cancer. EVIDENCE ACQUISITION EMBASE, MEDLINE, the Cochrane Database of Systematic Reviews, and other databases were searched from 1990 to July 2022. Randomised controlled trials (RCTs), nonrandomised comparative studies (NRCSs), and case series (CSs) were included. EVIDENCE SYNTHESIS We identified 107 studies, involving 9582 patients from two RCTs, 28 NRCSs, and 77 CSs. The quality of evidence is considered poor. Surgery is the mainstay of LN disease management, with early inguinal LN dissection (ILND) associated with better outcomes. Videoendoscopic ILND may offer comparable survival outcomes to open ILND with lower wound-related morbidity. Ipsilateral pelvic LN dissection (PLND) in N2-3 cases improves overall survival in comparison to no pelvic surgery. Neoadjuvant chemotherapy in N2-3 disease showed a pathological complete response rate of 13% and an objective response rate of 51%. Adjuvant radiotherapy may benefit pN2-3 but not pN1 disease. Adjuvant chemoradiotherapy may provide a small survival benefit in N3 disease. Adjuvant radiotherapy and chemotherapy improve outcomes after PLND for pelvic LN metastases. CONCLUSIONS Early LND improves survival in nodal disease in penile cancer. Multimodal treatments may provide additional benefit in pN2-3 cases; however, data are limited. Therefore, individualised management of patients with nodal disease should be discussed in a multidisciplinary team setting. PATIENT SUMMARY Spread of penile cancer to the lymph nodes is best managed with surgery, which improves survival and has curative potential. Supplementary treatment, including the use of chemotherapy and/or radiotherapy, may further improve survival in advanced disease. Patients with penile cancer with lymph node involvement should be treated by a multidisciplinary team.

Shan Y, Ding Z, Cui Z, Chen A. Incidence, prognostic factors and a nomogram of cervical cancer with distant organ metastasis: a SEER-based study. J OBSTET GYNAECOL 2023; 43:2181690. [PMID: 36927263 DOI: 10.1080/01443615.2023.2181690] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 03/18/2023]
Abstract
This study was to investigate the incidence, survival and prognostic factors of cervical cancer with distant organ metastasis, and to develop a nomogram to predict the prognosis of cervical cancer. We used the Surveillance, Epidemiology and End Results (SEER) database to screen patients diagnosed with cervical cancer from 2010 to 2014. The chi-squared test was used to analyse the differences in clinical characteristics, and we used Kaplan-Meier methods to perform survival analysis. Univariate and multivariate Cox proportional hazard regression models were used to estimate prognostic factors, and we developed a visual nomogram to judge the prognosis. We found that lung metastasis was the most common in cervical cancer patients with distant organ metastasis. Age, race, characteristics of the tumour, and therapy should be considered when analysing the prognosis of cervical cancer patients. The findings of this study may help clinicians to formulate individualised treatment strategies.Impact StatementWhat is already known on this subject? Distant organ metastasis of cervical cancer mainly involves lung, bone, liver and brain. Once it occurs, the survival and prognosis will be threatened seriously.What the results of this study add? 4176 patients were included, and lung metastasis was the most common in cervical cancer with distant organ metastasis (3.5%). Additionally, age, race, tumour grade, histological type, T-stage, N-stage, lung, liver and bone metastasis and the treatment mode are significantly related to the outcomes of cervical cancer patients. Furthermore, we developed a nomogram that could predict the probability of three-year and five-year OS.What the implications are of these findings for clinical practice and/or further research? The findings of this study may drive more and more studies focussing on the comprehensive prognostic assessment, diagnosis, and treatment of distant metastasis of cervical cancer. Besides, clinicians can utilise these findings to formulate individualised treatment strategies.

Robotic-Assisted Video-Endoscopic Inguinal Lymphadenectomy (RAVEIL) and Video-Endoscopic Inguinal Lymphadenectomy (VEIL) versus Open Inguinal Lymph-Node Dissection (OILND) in carcinoma of penis: Comparison of perioperative outcomes, complications and oncological outcomes. A systematic review and meta-analysis. Urol Oncol 2021; 40:112.e11-112.e22. [PMID: 34895995 DOI: 10.1016/j.urolonc.2021.11.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2021] [Revised: 10/12/2021] [Accepted: 11/08/2021] [Indexed: 12/09/2022]
Abstract
OBJECTIVE To perform a systematic review and meta-analysis evaluating the peri-operative outcomes, complications, and oncological outcomes of Robotic-Assisted Video-Endoscopic Inguinal Lymphadenectomy (RAVEIL)/Video-Endoscopic Inguinal Lymphadenectomy (VEIL) with Open Inguinal Lymph-Node Dissection (OILND) for management of inguinal lymph-nodes in carcinoma of the penis. METHODS A comprehensive literature search was performed in January 2021 using the PubMed, Embase, and Cochrane databases. Data from human studies comparing RAVEIL/VEIL vs. OILND in carcinoma of penis published in English was extracted and analyzed by two independent authors. RESULTS Two Randomised Controlled Trials and 6 cohort studies were included in the meta-analysis. RAVEIL/VEIL group exhibited increased operative time (Mean Difference [MD] = 15.28 [14.19; 16.38], P < 0.001), shorter hospital stay (MD = -1.06 [-1.14; -0.98], P < 0.001), and decreased duration of drainage (MD = -2.82 [-3.21; -2.43], P < 0.001), wound infection (Odds Ratio [OR] = 0.15 [0.08; 0.27], P < 0.001), skin necrosis (OR = 0.12 [0.05; 0.28], P < 0.001), lymphedema (OR = 0.41 [0.24; 0.72], P = 0.002), and major complications (OR = 0.11 [0.05; 0.24], P < 0.001) as compared to OILND group. Recurrence rate and number of deaths were comparable in both the groups. RAVEIL/VEIL groups showed slightly larger lymph-node yield (MD = 0.44 [0.18; 0.70], P < 0.001) as compared to OILND group. CONCLUSION RAVEIL/VEIL has lesser skin complications, lymphedema, and better lymph-node yield as compared to OILND. It is comparable in terms of lymphocele and recurrence. It has lesser hospital stay and duration of drainage but owing to heterogeneity, the results should be interpreted with caution. Further studies are required to determine long-term oncological outcomes like overall survival and disease-specific survival.

Abstract
BACKGROUND Few studies have explored the optimal examined lymph node count and lymph node density cutoff values that could be used to predict the survival of patients with penile cancer. We further clarify the prognostic value of lymph node density and examined lymph node count in penile cancer. METHODS The Surveillance, Epidemiology, and End Results (SEER) database was explored to recruit penile cancer patients from 2010 to 2015. A retrospective analysis of penile cancer patients' data from the First Affiliated Hospital of Anhui Medical University was performed for verification (2006-2016). The cutoff values of examined lymph node count and lymph node density were performed according to the ROC curve. Kaplan-Meier survival analysis was used to compare survival differences among different groups. Univariate and multivariate Cox proportional hazard regression analyses were used to determine the significant variables. On the basis of Cox proportional hazards regression model, a nomogram was established and validated by calibration plot diagrams and concordance index (C-index). RESULTS A total of 528 patients in the Surveillance, Epidemiology, and End Results cohort and 156 patients in the Chinese cohort were included in this study. Using the ROC curve, we found that the recommended cutoff values of ELN and LND were 13 and 9.3%, respectively (P <0.001). Kaplan-Meier curves suggested the significant differences of overall survival among different examined lymph nodes and lymph node density. Multivariate analysis indicated ELN and LND were independent prognostic factor for OS of penile cancer patients. Nomogram showed the contribution of ELN and LND to predicting OS was large. The C-index at 3-, and 5-year were 0.744 for overall survival (95% CI 0.711-0.777). CONCLUSIONS The more lymph nodes examined, the lower the density of lymph nodes, and the higher the long-term survival rate of penile cancer. We recommended 13 examined lymph nodes and lymph node density >9.3% as the cutoff value for evaluating the prognosis of penile cancer patients.

Log ODDS (LODDS) of positive lymph nodes as a predictor of overall survival in squamous cell carcinoma of the penis. J Surg Oncol 2021; 123:1836-1844. [PMID: 33684233 DOI: 10.1002/jso.26454] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2021] [Accepted: 02/23/2021] [Indexed: 01/27/2023]
Abstract
OBJECTIVE To evaluate the role of logarithmic ODDS (LODDS) in the number of positive lymph nodes and the number of negative lymph nodes as a prognostic metric in the squamous cell carcinoma (SCC) penis. METHODS Data were retrospectively collected from 96 cases of SCC penis that underwent bilateral groin dissection between 2010 and 2015 at our institute. Lymph node density (LND) and LODDS were calculated for all the patients and classified according to American Joint Committee on Cancer (AJCC) pN staging. Thresholds for LND (24% and 46%) and LODDS (-0.75 and 0) were established. Multivariate analysis of various cofactors was done with overall survival (OS) as a dependent factor. Three classification systems were compared using receiver operative characteristic (ROC) curve analysis. RESULTS Univariate analysis showed that AJCC pN, LND, and LODDS were all significantly correlated with OS. However, only LODDS (HR, 11.185; p = .023) remained an independent prognostic factor through multivariate analysis. LODDS (log-likelihood = 3832 vs. 3798; p < .001) had better prognostic performance than pN and better discriminatory ability than LND (AIC = 3902 vs. 3928). LODDS had better power of discrimination than LND and pN. LODDS could predict survival in lymph node yield (LNY) < 15 (p < .001). CONCLUSION LODDS is an independent predictor of OS in the SCC penis and has superior prognostic significance than the AJCC pN and LND classification systems.

Abstract
BACKGROUND Penile cancer represents a rare pathology whose natural history of treatment is poorly understood. OBJECTIVE To illustrate the dynamic survival profiles in surgically treated patients with squamous cell carcinoma of the penis (SCCP) using the conditional survival (CS) estimates. MATERIALS AND METHODS Patients with non-metastatic SCCP were identified from the Surveillance, Epidemiology, and End Results (SEER) database. Conditional 3-yr overall survival (OS) rate and 3-yr cancer-specific survival (CSS) rate represented the primary outcomes of interest and were calculated using the Kaplan-Meier method. The multivariable Cox regression model was employed to calculate proportional hazard ratios for the prediction of mortality. RESULTS A total of 1887 SCCP patients who had undergone surgeries were identified. Given a 1-, 2-, 3-, 4-, and 5-yr survivorship, the 3-yr OS rates were, respectively, improved by + 9.8 (72.6%), +18.2 (78.1%), +23.4 (81.6%), +27.8 (84.5%), and + 26.6% (83.7%) from those calculated at baseline (time zero). As compared with the baseline calculations, patients who had survived 1, 2, 3, 4, or 5 yr after surgery could, respectively, harvest a + 7.8 (84.7%), +14.8 (90.2%), +19.5 (93.9%), +22.1 (96.0%), and + 22.4% (96.2%) improvement in 3-yr CSS. Patients with the most aggressive disease at baseline ultimately benefited the most from event-free survivorship. Multivariable Cox regression analyses showed that the impact of adverse pathological parameters (G2-3, ≥ pT2, pN+) on OS and CSS mostly showed a decreasing trend over time and some could disappear after a minimum of 1-yr survivorship. DISCUSSION AND CONCLUSION The survival probability of SCCP patients increases with post-operative survival. Patients with aggressive disease at baseline ultimately benefit the most from event-free survivorship and may expect a better prognosis once they survive the critical few years after surgery. The recorded observations have crucial implications regarding patient counseling and follow-up.

Abstract
Introduction Our aim was to determine the relationship between surgical compliance and survival outcomes in patients with stage T1-2 non-small-cell lung cancer (NSCLC). Methods Patients with T1-2 NSCLC who were diagnosed between 2004 and 2015 were identified from the SEER database. Multivariate logistic regression was used to analyse factors associated with surgical compliance. Kaplan-Meier curves and Cox regression were used to analyse the effects of surgical compliance on overall survival (OS) and cancer-specific survival (CSS). Results Of the 221,704 eligible T1-2 NSCLC patients, 106,668 patients recommended surgery. Among them, 99,672 (93.4%) patients were surgical compliance group, and 6996 (6.6%) were surgical noncompliance group. Poor surgical compliance was associated with earlier diagnosis time, old age, male, black race, unmarried status, main bronchus site, poor grade/stage, and lower household income. Patients' compliance was an independent prognostic factor for OS and CSS of T1-2 NSCLC patients. Multivariate Cox regression showed that surgical noncompliance individuals showed lower OS (hazard ratio [HR] 2.494; 95% confidence interval [CI] 2.423-2.566, p < 0.001) and lower CSS (HR 2.877; 95% CI 2.782-2.974, p < 0.001) compared with surgical compliance patients. In addition, results in the non-surgical group were observed to be similar to those of the surgical noncompliance group. Conclusion We found that patients' compliance was an independent prognostic factor for survival in T1-2 NSCLC patients. Poor surgical compliance was associated with earlier diagnosis time, old age, male, black race, unmarried status, main bronchus site, poor grade/stage, and lower household income.

Abstract
Purpose This study aimed to establish a nomogram to predict the long‐term overall survival (OS) for patients with penile squamous cell carcinoma (PSCC). Method The PSCC patients receiving regional lymph node dissection (RLND) were enrolled from the Surveillance, Epidemiology, and End Results (SEER) database between 2004 and 2015. The dataset of all eligible patients were used to develop the predictive model. The significant independent predictors were identified through Cox regression modeling based on the Bayesian information criterion and then incorporated into a nomogram to predicted 1‐, 3‐, and 5‐year OS. Internal validation was performed using the bootstrap resampling method. The model performance was evaluated using Harrell's concordance index (C‐index), calibration plots, integrated discrimination improvement (IDI), net reclassification improvement (NRI), and decision curve analysis (DCA). Results Totally, 384 eligible PSCC patients were enrolled from the SEER database. A nomogram for OS prediction was developed, in which three clinical variables significantly associated with OS were integrated, including age, N classification, and log odds of positive lymph nodes (LODDS). The C‐index of the nomogram (0.746, 95% CI: 0.702‐0.790) was significantly higher than that of the American Joint Committee on Cancer (AJCC) staging system (0.692, 95% CI: 0.646‐0.738, P = .020). The bootstrap optimism‐corrected C‐index for the nomogram was 0.739 (95% CI: 0.690‐0.784). The bias‐corrected calibration plots showed the predicted risks were in good accordance with the actual risks. The results of NRI, IDI, and DCA exhibited superior predictive capability and higher clinical use of the nomogram compared with the AJCC staging system. Conclusion We successfully constructed a simple and reliable nomogram for OS prediction among PSCC patients receiving RLND, which would be beneficial to clinical trial design, patient counseling, and therapeutic modality selection.

Abstract
The present study aimed to investigate the association between surgical methods and survival outcomes in patients with astrocytoma. Patients diagnosed with astrocytoma between January 2004 and December 2015 were identified using the Surveillance, Epidemiology and End Results database. Kaplan-Meier curves and Cox regression were used to analyze the effects of surgical methods on overall survival (OS) and cancer-specific survival (CSS). Among 42,224 eligible patients with astrocytoma, 11,427 (27.1%) patients did not receive surgery, 7,661 (18.1%) received excisional biopsy (EB), 5,520 (13.1%) received a subtotal resection (STR), 6,037 (14.3%) received a gross resection (GR), 5,314 (12.6%) received a partial resection (PR) and 6,265 (14.8%) received a gross total resection (GTR). Patients who underwent GR had the longest survival time (17.00 months). However, over time, the proportion of patients who underwent STR or GR increased, whereas the proportion of patients who did not undergo surgery, PR or GTR decreased. Furthermore, surgical method was an independent prognostic factor for OS and CSS for the patients with astrocytoma. Multivariate Cox regression showed that GTR was associated with the more favorable OS [hazard ratio (HR), 0.80; 95% confidence interval (CI), 0.77-0.83; P<0.001] and CSS (HR, 0.80; 95% CI, 0.77-0.83; P<0.001) times compared with EB. Moreover, similar results were observed in subgroup analyses based on summary stage and grade. In the present study, it was demonstrated that GTR was one of the effective surgical methods for improved OS and CSS time in patients with astrocytoma. However, among the American astrocytoma population, the proportion of patients who underwent GTR decreased. It is necessary to further advocate for the efficacy of GTR.

Adjuvant radiation compares favorably to chemotherapy in patients with carcinoma penis and nodal positivity restricted to groin. Urol Oncol 2020; 38:641.e9-641.e18. [PMID: 32334927 DOI: 10.1016/j.urolonc.2020.03.026] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2019] [Revised: 03/18/2020] [Accepted: 03/25/2020] [Indexed: 11/21/2022]
Abstract
OBJECTIVES To compare overall survival (OS) between adjuvant radiation, chemotherapy and chemoradiation (CCRT) postsurgery for node-positive patients with carcinoma penis. METHODS Prospectively maintained registry for 45 patients receiving adjuvant treatment following lymph node dissection from 2011 to 2017, having minimum 6 months follow-up and more than 2 positive inguinal nodes was analyzed. Patients without pelvic nodal positivity (n= 32) were treated by radiotherapy (RT) (n = 25) or chemotherapy (n = 7); CCRT (n = 6) or chemotherapy (n = 7) was used in patients with positive pelvic nodes (n = 13). Data was collected for age, comorbidities, body mass index, tobacco exposure, treatment modality, tumor grade, pathological T and N stage, and extra-nodal extension. OS was compared between different treatment modalities stratifying patients with and without pelvic nodal positivity. Multivariate cox proportional hazard analysis was used to narrow down remaining variables and Inverse Probability Treatment Weights modeling was used to determine average treatment effect. RESULTS About 12 of 14 patients in the chemotherapy group received both cisplatin and paclitaxel. Pathological T stage, N stage and extra-nodal extension had significant association with OS on multivariate analysis. Among patients with nodal positivity restricted to groin the estimated average OS when all patients received adjuvant RT was 1,438 days (95% confidence interval [CI] 1,256-1,619 days, Pvalue <0.0001). The estimated average OS if all patients received chemotherapy was lower by 1,007 days (95% CI 810-1,202 days, P value <0.0001). Among patients with positive pelvic nodes the estimated average OS when all patients received adjuvant CCRT was 467 days (95% CI 368-566 days, P value <0.0001). The estimated average OS difference if all patients received chemotherapy was 17 days (95% CI -144 to 178 days, Pvalue 0.21). CONCLUSION In patients with nodal positivity limited to groin, adjuvant RT proved superior to chemotherapy. Among patients with pelvic nodal positivity, CCRT offers no significant OS advantage over combination chemotherapy.

Abstract
Aim: Our aim was to analyze the clinicopathological features of lung, liver, bone and brain metastasis in patients with endometrial cancer (EC). Patients & methods: We screened patients diagnosed with EC between 2010 and 2015 from the Surveillance, Epidemiology and End Results database. Results: Among 69,027 eligible EC patients, lung metastasis was the most common. Patients with lung or liver metastasis were at higher risk of bone and brain metastases than those without lung and liver metastasis. Brain metastasis has the lowest survival time (5.0 months) in single organ metastasis. Liver and brain metastasis have the highest death rate in two organ metastasis, and lung, liver and brain metastasis had the lowest survival time (1.0 month) in multi-sites metastasis. Conclusion: Lung metastasis was the most common in EC patients. Assessing distant organ metastasis may help clinicians to determine appropriate follow-up strategy for patients with EC.
