Hyalinizing clear cell carcinomas (HCCCs) are infrequent, malignant tumors characterized by their low-grade nature. They typically originate from minor salivary glands. However, these tumors can potentially emerge in any location with minor salivary glands, including the nasopharynx. This report presents two cases of HCCC in females aged 61 and 72 years, with both tumors approximately 4 cm in size. In the first case, a 72-year-old female presented with recurrent bilateral epistaxis. Imaging studies revealed a nasopharyngeal mass, surgically excised, and histopathological analysis confirmed HCCC. Postoperatively, the patient received combined chemotherapy and radiotherapy, achieving a recurrence-free status 2.5 years later. The second case involves a 61-year-old female with a two-year history of bloody nasal discharge. Imaging studies identified a nasopharyngeal lesion, surgically removed, and histopathological examination confirmed HCCC. This patient underwent radiotherapy followed by combination chemotherapy with paclitaxel and carboplatin, displaying no signs of recurrence upon reevaluation after 10 months. These cases highlight the successful management of HCCC through a comprehensive, multimodal approach, integrating surgical intervention and adjuvant therapy. The favorable outcomes emphasize the significance of a thorough treatment strategy for HCCC in the nasopharynx, providing valuable insights for clinicians. Further studies are essential to enhance our understanding of this rare entity and refine treatment protocols for optimized patient outcomes.

OBJECTIVE: The objective of the study was to assess the effectiveness and toxicity of platinum-based adjuvant chemoradiotherapy (POCRT) in comparison to postoperative radiotherapy (PORT) in patients with head and neck adenoid cystic carcinoma (HNACC).
METHODS: This retrospective study analyzed patients diagnosed with HNACC at our center between January 2010 and April 2020. A 1:1 propensity score matching method was used to create a matched cohort.
RESULTS: In this study, 206 patients were analyzed, with 147 patients (71.4%) receiving postoperative radiotherapy (PORT) and 59 patients (28.6%) receiving POCRT. Twenty-one patients experienced local-regional failure. The 3-, 5-, and 10-yr local-regional control (LRC) rate for the cohort were 92.0%, 90.6%, and 86.9%, respectively. In both the entire cohort and the matched cohort, the POCRT group exhibited superior LRC compared to the PORT group (Gray\'s test, all P < 0.05*). Multivariate analysis identified adjuvant concurrent chemotherapy as an independent prognostic factor for LRC (Competing risks regression, HR = 0.144, 95% CI 0.026-0.802, P = 0.027*). In addition, the POCRT group had higher incidences of upper gastrointestinal toxicity and hematologic toxicities, including leukopenia, neutropenia, and anemia (all P < 0.05*).
CONCLUSIONS: In terms of reducing locoregional failures in HNACC patients, POCRT may potentially offer a more effective therapeutic approach than using PORT alone, although it also entails an augmented burden of treatment-related toxicity.

BACKGROUND: Although the role of adjuvant chemotherapy (CT) for resectable biliary tract cancer (BTC) is gradually recognized, the benefit of adjuvant chemoradiotherapy (CRT) is still controversial. Our study is designed to compare the prognosis of CRT versus CT in BCT patients.
METHODS: Clinicopathologic characteristics of patients with operable gallbladder cancer (GBCA), intrahepatic bile duct cancer (IHBDC), or extrahepatic bile duct cancer (EHBDC) were obtained from the Surveillance, Epidemiology and End Results (SEER) database (2004-2015). Univariate and multivariate analyses were performed to identify prognostic factors for overall survival (OS). Selection bias were reduced by propensity-score matching (PSM). Kaplan-Meier analysis was used to estimate the survival time.
RESULTS: Within 922 patients, 53.9% received adjuvant CRT, and 46.1% received adjuvant CT. Multivariate analysis showed age, primary tumor site, T stage, N stage, tumor size, number of removed lymph nodes, and treatment were independent risk factors for OS. Similar improvement of CRT on survival was identified by PSM in the matched cohort compared with CT (28.0 months vs. 25.0 months, p = 0.033), particularly in GBCA cohort (25.0 months vs. 19.0 months, p = 0.003). Subgroup analysis indicated CRT improved outcomes of patients with age ≥ 60, female, lymph nodes positive, tumor size ≥ 5 cm, and none removed lymph node diseases.
CONCLUSIONS: Adjuvant CRT correlated with improved survival in patients with resected BTC compared with adjuvant CT, particularly in GBCAs. In addition, patients with age ≥ 60, female, lymph nodes positive, tumor size ≥ 5 cm, and none removed lymph node diseases may receive more benefits from adjuvant CRT.

UNASSIGNED: The prognosis of gallbladder cancer (GBC) is dismal. This study aimed to compare the outcomes of adjuvant chemoradiotherapy (ACR) with those of surgery alone (S) and adjuvant chemotherapy (AC).
UNASSIGNED: The Surveillance, Epidemiology, and End Results (SEER) Program database was used to identify patients diagnosed with GBC and undergoing surgery between 2004 and 2015. The patients were divided into the S, AC, and ACR groups according to their treatment. Categorical variables were compared by Pearson\'s chi-square test, and a 1:1:1 propensity score matching analysis (PSM) was performed. Overall survival was assessed by Kaplan-Meier curves with log-rank tests. Subgroup analyses were conducted.
UNASSIGNED: A total of 5451 patients were identified in the SEER database. After PSM, the two-year survival among patients who received S, AC, and ACR was 36%, 39%, and 45%, respectively. ACR was associated with improved two-year survival (p < 0.001), while the survival rates were similar in the AC and S groups (p = 0.127) but better in the ACR group than in the AC group (p = 0.012). Subgroup analyses indicated that while the two-year survival rates did not differ significantly in stage II GBC patients between the groups (all p > 0.05), ACR was associated with significantly improved two-year survival in stage Ⅲa (p = 0.008), Ⅲb (p < 0.001), and Ⅳb (p < 0.001) GBC patients.
UNASSIGNED: The combination of surgery and ACR as the treatment modality provided greater survival benefits for GBC patients, particularly for those with advanced tumor staging.

Endometrial cancer is one of the most common gynecological cancer in the world. However, the available adjuvant therapies, chemotherapy (CT) and radiotherapy (RT), demonstrated several limitations when used alone. Therefore, we conducted a meta-analysis to investigate the clinical effectiveness of chemoradiotherapy (CRT) based on overall survival (OS) and disease-free survival (DFS).
A literature search was performed on five databases and one clinical trial registry to obtain all relevant articles. Search for studies was completed on September 9, 2021. A meta-analysis was conducted to determine the overall hazard ratio with the 95% Confidence Interval.
A total of 17 articles with 23,975 patients in the CRT vs RT group and 50,502 patients in the CRT vs CT group were included. The OS Hazard Ratios (HR) of CRT compared to RT was 0.66 (95% CI [0.59-0.75]; P < 0.00001). Compared to CT, the OS HR was 0.70 (95% CI [0.64-0.78]; P < 0.00001). CRT also significantly improved the DFS compared to CT only (HR 0.79, 95% CI [0.64-0.97]; P = 0.02) However, CRT did not improve the DFS compared to RT only, with HR of 0.71 (95% CI [0.46-1.09]; P = 0.12).
Adjuvant CRT can significantly improve OS compared to CT or RT alone and improve the DFS compared to CT alone in patients with advanced endometrial cancer. Further research is needed to identify the optimal CRT regimen, and to whom CRT will be most beneficial.

UNASSIGNED: The aim of this study was to investigate the recurrence patterns in pancreatic cancer patients treated with adjuvant intensity modulated radiotherapy (IMRT) and to correlate the sites of locoregional recurrence with radiotherapy target volumes.
UNASSIGNED: Thirty-eight patients who had undergone resection and adjuvant chemoradiation for pancreatic cancer were evaluated. Radiotherapy (RT) was started after 1-3 cycles of adjuvant chemotherapy (CHT). Clinical target volume (CTV) was contoured according to the RTOG guideline. All patients were treated with IMRT with a dose of 45-50.4 Gy. Computerized tomography (CT) images at the time of recurrence were correlated with radiotherapy plans. Locoregional recurrences were classified as in-field, out-field and marginal.
UNASSIGNED: Median overall survival (OS) was 19 months. One- and 2-year OS rates were 73.6% and 37.1%, respectively. Locoregional recurrence and distant metastases were observed in 11 (28.9%) and 23 (60.5%) patients, respectively. For the 11 locoregional recurrences, 7 were in-field, 1 was marginal, and 3 were out-of-field. One patient had isolated local, 2 patients had isolated regional and 15 (57.6%) patients had only distant failures. The first presentations of failures were mostly distant (58%). On multivariate analysis, tumor size ≥ 3 cm (p = 0.011) and positive vascular invasion (p = 0.014) predicted for worse OS rate.
UNASSIGNED: The majority of locoregional recurrences were in the radiation field among pancreatic cancer patients treated with postoperative IMRT. However, failures were predominantly distant, and improvement of systemic control may be of particular interest.

BACKGROUND: For Siewert type II/III adenocarcinoma of gastroesophageal junction (AGE), the efficacy of adjuvant chemoradiotherapy (CRT) after D2/R0 resection remains uncertain.
OBJECTIVE: To determine whether CRT was superior to chemotherapy (CT) alone after D2/R0 resection for locally advanced Siewert type II/III AGE.
METHODS: We identified 316 locally advanced Siewert type II/III AGE patients who were treated with D2/R0 resection at National Cancer Center from 2011 to 2018. 57 patients received adjuvant CRT and 259 patients received adjuvant CT. We followed patients for overall survival (OS), relapse-free survival, and recurrence pattern.
RESULTS: Five-year OS rates of the CRT group and the CT group for all patients were 66.7% and 41.9% (P = 0.010). Five-year OS rates of the CRT group and the CT group for Siewert type III AGE patients were 65.7% and 43.9% (P = 0.006). Among the 195 patients whose recurrence information could be obtained, 18 cases (34.6%) and 61 cases (42.7%) were diagnosed as recurrence in the CRT group and CT group, respectively. The local and regional recurrence rates in the CRT group were lower than that in the CT group (22.2% vs 24.6%, 27.8% vs 39.3%). Multivariable cox regression analysis showed that vascular invasion, nerve invasion, and adjuvant CRT were important prognostic factors for Siewert type III AGE.
CONCLUSIONS: For locally advanced Siewert type III AGE, adjuvant CRT may prolong OS and reduce the regional recurrence rate.

BACKGROUND: The most frequently diagnosed primary brain tumor is glioblastoma (GBM). Nearly all patients experience tumor recurrence and up to 90% of which is local recurrence. Thus, increasing the therapeutic ratio of radiotherapy using hypofractionated stereotactic radiotherapy (HSRT) can reduce treatment time and may increase tumor control and improve survival. To evaluate the efficacy and toxicity of the combination of HSRT and intensity-modulated radiotherapy (IMRT) with temozolomide after surgery in GBM patients and provide evidence for further randomized controlled trials.
METHODS: HSCK-010 is an open-label, single-arm phase II trial (NCT04547621) which includes newly diagnosed GBM patients who underwent gross total resection. Patients will receive the combination of 30 Gy/5fx HSRT, and 20 Gy/10fx IMRT adjuvant therapy with concurrent temozolomide and adjuvant chemotherapy. The primary endpoint is overall survival (OS). Secondary outcomes include progression-free survival (PFS) rate, objective-response rate (ORR), quality of life (Qol) before and after the treatment, cognitive function before and after the treatment, and rate of treatment-related adverse events (AE). The combination of HSRT and IMRT with temozolomide can benefit the patients after surgery with good survival, acceptable toxicity, and reduced treatment time.
BACKGROUND: NCT04547621 . Registered on 14 September 2020.

UNASSIGNED: To compare the survival benefit in the adjuvant chemoradiotherapy (CRT) group and chemotherapy (CT) group for stage III gastric or gastroesophageal junction (GEJ) cancer after D2/R0 resection.
UNASSIGNED: From January 2011 to May 2018, 819 patients (CRT group: 215 patients, CT group: 604 patients) diagnosed as pathological stage III after D2/R0 resection were retrospectively collected and the survival and recurrence patterns were analyzed. The baseline characteristics were balanced based on propensity score matching (PSM). The survival benefit was compared between two groups using Kaplan-Meier analysis and Cox regression model.
UNASSIGNED: The 5-year overall survival (OS) rate in the CRT group was significantly higher than that in the CT group whether before or after the PSM. The multivariate Cox regression analysis identified the significant poor OS in patients with advanced TNM stage (P < 0.001) and patients who did not receive the adjuvant CRT (P = 0.008). For the recurrence patterns, 85 (39.5%) patients in the CRT group and 300 (49.7%) patients in the CT group were diagnosed as recurrence (P = 0.011). The regional recurrence in the CRT group was less than that in the CT group (20.5% vs. 35.1%, P = 0.028).
UNASSIGNED: For patients diagnosed as stage III gastric cancer or gastroesophageal junction cancer, the addition of adjuvant chemoradiotherapy will significantly improve the overall survival and regional control.

UNASSIGNED: This study aimed to explore the effects of our rational emotive behavior therapy (REBT) program on symptoms, anxiety, depression, and sleep state in patients with colorectal cancer (CRC) undergoing chemotherapy.
UNASSIGNED: From October 2020 to May 2021, fifty-six patients with CRC in a hospital in the Hunan Province were randomly divided into an intervention group (n = 28) and a control group (n = 28). The patients in the intervention group completed a 6-week REBT program based on routine nursing care, including four courses: 1) establish a relationship and formulate health files; 2) group communications and study symptom management; 3) continuously provide health knowledge and strengthen healthy behavior; and 4) review the treatment and summary. The control group maintained routine nursing care. The simplified Chinese version of the Memorial Symptom Assessment Scale Short Form (MSAS-SF-SC), the Hospital Anxiety and Depression Scale (HADS), and the Pittsburgh Sleep Quality Index (PSQI) scale were used to investigate and compare the intervention effects of the two groups at baseline (T1, before the intervention), four weeks (T2), and six weeks (T3) after the intervention.
UNASSIGNED: The intervention group was significantly improved in symptoms, anxiety, depression, and sleep state, compared with the control group. At T2, MSAS-SF-SC (24.43 ± 4.26 vs.28.07 ± 3.91), symptom distress (17.29 ± 4.04 vs. 19.39 ± 3.59), symptom frequency (7.14 ± 1.51 vs. 8.68 ± 1.42), HADS (13.68 ± 3.38 vs. 15.86 ± 3.79), anxiety (3.89 ± 1.85 vs. 5.18 ± 2.18), and depression (9.79 ± 2.06 vs. 10.68 ± 2.23), showed that the difference between the two groups was statistically significant (P < 0.05). At T3, MSAS-SF-SC (23.89 ± 3.54 vs. 30.14 ± 3.94), symptom distress (17.61 ± 3.52 vs. 21.32 ± 3.57), symptom frequency (6.29 ± 1.49 vs. 8.82 ± 1.47), HADS (11.82 ± 2.57 vs. 16.29 ± 3.13), anxiety (3.21 ± 1.64 vs. 5.61 ± 1.77), and depression (8.61 ± 1.52 vs. 10.68 ± 1.81), showed that the difference between the two groups was statistically significant (P < 0.05). The sleep state of the intervention group was better than the control group at T3, with decreased score of PSQI [4.00 (3.00,8.00) vs. 9.00 (7.00,12.50), Z = -3.706, P < 0.001].
UNASSIGNED: The 6-week REBT program can effectively improve the symptom, anxiety, depression, and sleep state of patients with CRC undergoing chemotherapy, which could as a care plan for patients with CRC who are repeatedly admitted to the hospital for chemotherapy.
