This was a prospective study of a patient with vaginal adenocarcinoma after previous simple hysterectomy. The technique of radical parametrectomy with vaginectomy and pelvic and aortic lymphadenectomy as used for open cases for years was performed laparoscopically. The operating time was 270 min, the estimated blood loss was 200 mL, and the duration of hospitalization was 3 days. There were no intraoperative or postoperative complications. Radical parametrectomy with vaginectomy and pelvic and aortic lymphadenectomy can be successfully accomplished laparoscopically.

In all, 1,128 patients were randomly assigned to the test (n = 564) or validation group (n = 564). In the test group, ten pretreatment factors (age, gender, performance status, primary tumor, number of involved vertebrae, ambulatory status, other bone metastases, visceral metastases, interval from cancer diagnosis to radiotherapy of MSCC, time to developing motor deficits) plus the radiation regimen were retrospectively evaluated. Factors significantly associated with survival on multivariate analysis were included in the survival score. The score for each factor was determined by dividing the 6-month survival rate (%) by 10. The prognostic score represented the sum of the scores for each factor. In the multivariate analysis of the test group, age, performance status, primary tumor type, ambulatory status, other bone metastases, visceral metastases, interval from cancer diagnosis to radiotherapy of MSCC, and time to developing motor deficits were significantly associated with survival. Total scores ranged from 25 to 57 points. In the test group, 6-month survival rates were 11 % for 25-39 points, 56 % for 40-48 points, and 97 % for 49-57 points (p < 0.001). In the validation group, 6-month survival rates were 10, 53, and 94 %, respectively (p < 0.001). Based on the survival scores of the test group, three prognostic groups were identified. The survival rates of the validation group were similar to the test group. This score appears reproducible and can help select the appropriate treatment for elderly patients with MSCC.

Patients included on this clinical trial were beginning thoracic radiation therapy to the mediastinum. Following stratification, they were randomized, in a double-blind manner, to receive a sucralfate solution or an identical-appearing placebo solution. Esophagitis was measured by physicians who used standard criteria and also by patients who used short questionnaires completed weekly during the course of the trial. A total of 97 assessable patients were entered onto this clinical trial. During the first 2 weeks of the study, two placebo patients (4%) stopped their study medication, compared with 20 sucralfate patients (40%). This was related to substantially increased incidences of gastrointestinal toxicity (58% of sucralfate patients v 14% of placebo patients; P > .0001). There was no substantial benefit from the sucralfate in terms of esophagitis scores. This oral sucralfate solution does not appear to inhibit radiation-induced esophagitis and is associated with disagreeable gastrointestinal side effects in this patient population.

Methods: The NCDB database was queried to identify patients with stage IV bronchopulmonary NE tumors treated between the years of 2004-2012. Patients were split into two groups based on the presence of brain metastases at diagnosis and survival probabilities with multivariate models were performed. Results: A total of 7,725 patients with Stage IV bronchopulmonary NE tumors were identified. The histological subtypes studied in this cohort were NE carcinoma (65.4%), large cell NE carcinoma (30.5%), typical carcinoid (2.8%) and atypical carcinoid (1.3%) . The patients included in this study were mainly white (86.4%) men (56.8%) with a median age of 67 years who had liver (9.5%), bone (6.2%) and brain (5.9%) metastases at diagnosis. The median overall survival (OS) of the cohort was 5.59 (95% CI: 5.4-5.8) months, but when OS was stratified by histological subtype it was significantly better in patients with typical carcinoid (table). In the whole cohort, the median OS did not differ between patients with and without brain metastases (5.55 vs. 5.68; p = 0.24). However, a sensitivity analysis by histology showed that the presence of brain metastases worsen the median OS of patients with typical carcinoid only (15.1 vs 4.6, p = 0.04). An adjusted multivariate analysis restricted to patients with brain metastases showed that administration of systemic chemotherapy (HR:0.5; 95% CI:0.35-0.72, p < 0.001) and resection of distant metastases (HR:0.5; 95% CI:0.29-0.88, p = 0.017) were the two most powerful independent prognostic factors. Conclusions: The presence of brain metastases negatively impact survival of patients with typical carcinoids but not in those with the other histological subtypes included in this study. Staging MRI should be strongly considered at diagnosis in patients with bronchopulmonary NE tumors, due to the sizable proportion of these patients presenting with brain metastases and also due to its prognostic value in a subset of this population.

However, a subset of SCLC achieves long‐term survival. The objective of this study was to investigate factors and pattern of long‐term survival in patients with limited‐stage small cell lung cancer (LS‐SCLC) who achieved a complete response (CR) after chemoradiotherapy.Patient and MethodsThis was a single‐center retrospective study. The analysis of hazard ratio (HR) and 95% confidence interval (CI) was performed using Cox proportional hazards model. For pattern analysis, the date of recurrence was used as the endpoint. The nominal categorical variables were analyzed by the χ2 test. Survival was estimated using the Kaplan–Meier model, and the results were reported as the median and interquartile range.ResultsWe identified 162 patients, median age was 64.7 (56.2–70.2) years, and 94 (58%) were females. Eighty‐one patients (50%) had recurrence during follow‐up. Gastroesophageal reflux disease (GERD) (HR, 0.65; 95% CI, 0.45–0.93; p = 0.016) and neurological paraneoplastic syndrome (PNS) (HR, 0.46; 95% CI, 0.29–0.72; p < 0.001) were independent factors associated with improved overall survival (OS). Patients with GERD had prolonged recurrence free survival (RFS) compared to patients without GERD (median, 29.1 months vs. 13.9 months, p < 0.001), whereas patients with neurological PNS had a reduced recurrence rate compared to those patients without neurological PNS (No. [%], 8 [20.5] vs. 73 [59.3], p < 0.001).ConclusionsPatients with LS‐SCLC achieving a CR after chemoradiotherapy, GERD, and neurological PNS were associated with improved OS. GERD and neurological PNS were associated with longer RFS and lower recurrence rate, respectively.

Anticipation of treatment may cause distress and sleep disorders. This study aimed to identify risk factors for sleep disorders. Patients and Methods: In 42 patients with rectal or anal cancer scheduled for radiotherapy, 16 characteristics were analyzed for associations with pre-radiotherapy sleep disorders including age, gender, performance score, comorbidity, patient’s or family history of additional cancer/melanoma, distress score, emotional/physical/practical problems, tumor site and stage, surgery and relation to COVID-19 pandemic. Results: Overall prevalence of pre-radiotherapy sleep disorders was 42.9%. Sleep disorders were significantly associated with Karnofsky performance score 60-80 (p=0.044), Charlson comorbidity index ≥3 (p=0.0012), distress score 6-10 (p=0.00012), and more emotional (p=0.0012), physical (p=0.0004) or practical (p=0.033) problems. A trend was found for female gender (p=0.061). Conclusion: Sleep disorders were common in patients with rectal or anal cancer scheduled for radiotherapy. Risk factors can help identify patients requiring psychooncological support already prior to the start of radiotherapy.
