Major and minor salivary gland cancers: A multicenter retrospective study.

BACKGROUND: Most of the studies on salivary gland cancers are limited for various reasons such as being single-center, small number of patients, including only major or minor SGCs, or only including epidemiological data. METHODS: A total of 37 medical oncology clinics from different regions of Turkey participated in this retrospective-multicenter study. The analyzed data included clinical and demographical features, primary treatment, metastasis localizations, and treatments and includes certain pathologic features. RESULTS: The study included data from a total of 443 SGCs. 56.7% was in major salivary glands and 43.3% was in minor salivary glands. Distant metastasis in the major SGCs was statistically significantly more common than in the minor SGCs, locoregional recurrence was statistically significantly more common in the minor SGCs than in the major SGCs (p = 0.003). CONCLUSIONS: Epidemiological information, metastasis and recurrence patterns, treatment modalities, and survival analysis of the patients over 20 years of follow-up are presented.

Cisplatin plus paclitaxel and bevacizumab versus carboplatin plus paclitaxel and bevacizumab for the first-line treatment of metastatic or recurrent cervical cancer.

OBJECTIVE: Cisplatin-paclitaxel and bevacizumab is a frequently used treatment regimen for metastatic or recurrent cervical cancer, and carboplatin-paclitaxel and bevacizumab are also among the recommended regimens. In this study we aimed to evaluate the efficacy of these two regimens for the treatment of metastatic or recurrent cervical cancer. METHODS: Patients with metastatic or recurrent cervical cancer treated with cisplatin-paclitaxel and bevacizumab or carboplatin-paclitaxel and bevacizumab were retrospectively evaluated in this study. The clinical and demographic characteristics of patients in each group were evaluated. Median overall survival, progression-free survival, and response rates between the two groups were compared. RESULTS: A total of 250 patients were included. Overall, the numbers of patients with recurrent disease and metastatic disease were 159 and 91, respectively. The most common histologic subtype was squamous cell carcinoma (83.2%). The median duration of follow-up was 13.6 (range 0.5-86) months. The median progression-free survival was 10.5 (95% CI 9.0 to 11.8) months in the cisplatin-paclitaxel and bevacizumab group (group 1), and 10.8 (95% CI 8.6 to 13.0) months in the carboplatin-paclitaxel and bevacizumab group (group 2) (HR 1.20; 95% CI 0.88 to 1.63; p=0.25). The median overall survival was 19.1 (95% CI 13.0 to 25.1) months in group 1 and 18.3 (95% CI 15.3 to 21.3) months in group 2 (HR 1.28; 95% CI 0.91 to 1.80; p=0.15). CONCLUSIONS: There is no survival difference between cisplatin or carboplatin combined with paclitaxel and bevacizumab in metastatic or recurrent cervical cancer.

Survival outcome of pulmonary metastasectomy among the patients with colorectal cancers.

OBJECTIVE: Pulmonary metastasectomy for the treatment of metastatic colorectal cancer is essential, but high ranked evidence of survival benefit is lacking. Here, we aimed to examine the prognostic factors after pulmonary metastasectomy in patients with colorectal cancer. METHODS: This is a single-center, retrospective hospital-based observational case series study. We reviewed data for 607 patients with metastatic colorectal cancer (mCRC) who were treated and observed from 2012 to 2019. Of the 607 patients with mCRC, 87 were with solitary lung metastases. Of the 87 patients, 39 were not appropriate for metastasectomy, while 15 patients recognized as suitable candidates by the multidisciplinary thoracic tumor board rejected metastasectomy. Consequently, only 33 patients were included in the final analysis. RESULTS: Rectum was detected as the primary site in 16 (48.5%) patients. Over 80% of patients had metachronous lung metastases, with a median of 29.0 months from initial diagnosis. Video-assisted thoracic surgery with wedge resection was performed in 20 (60.6%) patients. Over 90% of patients had solitary metastasis resected, with 97% of R0 resection. Median tumor size was 23.0 mm (min: 10; max: 90). Adjuvant treatment was given to 31 (93.9%) patients, while neoadjuvant treatment was given only to 8 (25%) patients. Of the 33 patients, there were 25 (75.7%) relapses. The most frequent site of relapse was lung in 15 (45.5%) patients. Interestingly, there were only 4 (12.2%) patients who had a relapse in the liver after lung metastasectomy. We found that median disease-free survival (DFS) and overall survival (OS) were 43.0 (13.0-73.0) and 55.0 (31.6-78.4) months, respectively. CONCLUSIONS: Pulmonary metastasectomy was associated with significantly long-time survival rates in mCRC (43 months of DFS and 55 months of OS). The second relapse occurred in 25 (75.7%) patients, with isolated lung metastases in nearly half of the patients (45.5%). Therefore, lung metastases in mCRC were unique and a multidisciplinary team including a thoracic surgeon should manage these patients.

Endocan and albuminuria in type 2 diabetes mellitus.

BACKGROUND: Endocan is a newly identified proteoglycan released from endothelium, stimulating angiogenesis and when increased, indicates endothelial activation (inflammation). Our aim was to examine the association between serum endocan levels and urine albumin-creatinine ratio (UACR). METHOD: One hundred and thirty-seven patients with type 2 diabetes mellitus and normal serum creatinine who had no co-morbidities other than hypertension, diabetic nephropathy, retinopathy, or neuropathy were divided into normoalbuminuria (G1), microalbuminuria (G2), and macroalbuminuria (G3) groups and compared cross-sectionally regarding serum endocan levels. RESULT: There were 55, 47, and 35 patients in G1, G2, and G3, respectively. The groups were comparable in terms of gender, age, duration of diabetes, diabetic neuropathy/retinopathy, fasting glucose, HbA1c, serum creatinine level, and eGFR. Patients in G3 had significantly higher blood pressure but lower serum albumin and endocan levels. UACR showed a negative bivariate correlation with serum endocan levels (r = -.282, p = .001). There was bivariate positive correlation between endocan and systolic blood pressure (r=.185, p = .030). In linear regression analysis, UACR was negatively correlated with endocan while positively correlated with systolic blood pressure, duration of diabetes, and platelet distribution width. CONCLUSION: Patients with macroalbuminuria had lower endocan levels, and increasing UACR was associated with decreasing serum endocan levels. Despite the occurrence of angiogenesis and glomerular hypertrophy in the early phase of diabetic nephropathy, ensuing significant renal injury over time may reduce the expression of endocan. Serum endocan levels may represent a novel marker for nephropathy progression.
