Introduction The ideal time interval between the completion of chemoradiotherapy and subsequent surgical resection of advanced stage rectal tumors is highly debated. Our aim is to study the effect of the time interval between the completion of chemoradiotherapy and surgical resection on postoperative and oncologic outcomes in rectal cancer. Methods Patients who underwent neoadjuvant chemoradiotherapy for resected locally advanced rectal tumors between 2004 and 2015 were included in this analysis. The time interval was calculated from the date of radiation completion to date of surgery. Patients were split into 2 groups based on the time interval (<8 weeks and >8 weeks). Postoperative outcomes (anastomotic leak, pathologic complete response (pCR), and readmission) and survival were assessed with multivariable logistic regression and Cox regression models while adjusting for relevant confounders. Results 200 patients (62% male) underwent resection with a median time interval of 8 weeks from completion of radiotherapy. On multivariable logistic regression, there was no significant increase in odds between time interval to surgery and anastomotic leak (aOR = .8 [.27-2.7], P = .8), pCR (aOR = 1.2[.58-2.6] P = .6), or readmission (aOR = 1.02, 95% CI:0.49-2.24, P = .9). Time interval to surgery was not an independent prognostic factor for overall (HR = 1.04 CI = .4-2.65, P = .9) and disease-free survival (HR = 1.2 CI = .5-2.9, P = .6). Conclusion The time interval between neoadjuvant radiotherapy completion and surgical resection does not affect anastomotic leak rate, achievement of pCR, or overall and disease-free survival in patients with rectal cancer. Extended periods of time to surgical resection are relatively safe.

Abstract Background Combined hepatocellular carcinoma and cholangiocarcinoma (cHCC-CC) is an infrequent type of primary liver cancer that comprises hepatocellular carcinoma (HCC) and cholangiocarcinoma (CC). This study investigated the clinicopathological features and prognosis among cHCC-CC, HCC, and CC groups. Methods We prospectively collected the data of 608 patients who underwent surgical resection for liver cancer between 2011 and 2018 at E-Da Hospital, I-Shou University, Kaohsiung, Taiwan. Overall, 505 patients with cHCC-CC, HCC, and CC were included, and their clinicopathological features, overall survival (OS), and recurrence were recorded. OS and recurrence rates were analyzed using the Kaplan–Meier analysis. Results In the entire cohort, the median age was 61 years and 80% were men. Thirty-five (7.0%) had cHCC-CC, 419 (82.9%) had HCC, and 51 (10.1%) had CC. The clinicopathological features of the cHCC-CC group were more identical to those of the HCC group than the CC group. OS was significantly lower in the cHCC-CC group than in the HCC group but was not significantly higher in the cHCC-CC group than in the CC group. The median OS of cHCC-CC, HCC, and CC groups was 50.1 months [95% confidence interval (CI): 38.7–61.2], 62.3 months (CI: 42.1–72.9), and 36.2 months (CI: 15.4–56.5), respectively. Cumulative OS rates at 1, 3, and 5 years in cHCC-CC, HCC, and CC groups were 88.5%, 62.2%, and 44.0%; 91.2%, 76.1%, and 68.0%; and 72.0%, 48.1%, and 34.5%, respectively. After propensity score matching (PSM), OS in the cHCC-CC group was not significantly different from that in the HCC or CC group. However, OS was significantly higher in the HCC group than in the CC group before and after PSM. Furthermore, the disease-free survival was not significantly different among cHCC-CC, HCC, and CC groups before and after PSM. Conclusion The clinicopathological features of the cHCC-CC group were more identical to those of the HCC group than the CC group. The OS rate was significantly lower in the cHCC-CC group than the HCC group. However, after PSM, OS and disease-free survival in the cHCC-CC group were not significantly different from those in the HCC or CC group.

Abstract Background Primary mucosal melanoma of the head and neck (MMHN) is a rare, aggressive tumor of neural-crest origin. Despite universal progress in cancer care, the prognosis of MMHN continues to remain dismal. Aims To analyze and report the outcomes of primary head and neck mucosal melanomas treated at Tata Memorial Hospital. Methods Retrospective chart review of all patients with a diagnosis of nonocular MMHN presenting to the institute between 1995 to 2003. Locoregional control and disease-free survival were used as outcome measures. Results 42 patients presenting within the study period with nonocular MMHN (oral-55%, sinonasal-40%, and pharyngeal-5%) at a median age of 53 years constituted the demographic cohort. 11 (26%) patients not amenable to any active anticancer treatment were treated with best supportive care alone and excluded from outcome analysis. 26 patients underwent surgery with complete resection of tumor. Seven (27%) also received adjuvant radiotherapy due to the adverse histopathologic features. Two patients were treated with radical radiotherapy due to unresectability, two patients received palliative chemotherapy, while one patient was treated with definitive chemoradiotherapy. With a mean follow-up of 11 months (range 1-58 months), the 3-year locoregional control and disease-free survival was 41% and 12% respectively. Age, sex, site of primary, tumor stage, surgical resection, margin status, depth of infiltration, and adjuvant radiotherapy did not affect outcome significantly. Conclusion Primary mucosal melanoma of the head and neck is a rare, but, aggressive tumor with a dismal prognosis. Surgical resection with clear margins offers the best chance of cure for early localized disease. The high incidence of locoregional as well as distant failures after surgical resection supports the use of adjuvant therapy. Deeper insights into the pathobiology of disease can help develop more specific and effective treatment strategies to improve long-term outcomes.
