Article Abstract
Backgrounds: Oncological outcomes of the robotic low anterior rectal resection with total mesorectal excision (TME) are still under discussion. Few studies have proven that robotic TME (rTME) is a safe and equivalent method for treatment of rectal carcinoma. But there is almost no comparison between the rTME and conventional TME in terms of the number of lymph nodes obtained and the quality of the TME.
Methods: A single institution retrospective study was designed in a cohort of 261 patients. Cohort was divided into two groups depending on the type of surgery (rTME versus TME) and within these two groups, patients were divided according to whether they underwent neoadjuvant chemoradiation (nCHRT) or did not. The primary objective of the study was to compare obtained number of the lymph nodes in specimen. Secondary objectives were comparison of the quality of the TME and the number of positive circumferential resection margins.
Results: Results of the study have shown no significant difference in number of the lymph nodes obtained by the rTME and TME. There was no difference in the quality of the TME, neither in the group with the previous nCHRT nor in the group without a nCHRT.
Conclusion: With results from the study we consider the rTME to be non-inferior to the conventional TME. Therefore, at least identical oncological results can be expected in patients treated by the rTME.

Enhancing diagnostic precision: a multicentric study of endobronchial ultrasound-guided transbronchial mediastinal cryobiopsy in lymphoproliferative disorders.

Background: The diagnostic accuracy of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) for the diagnosis of lymphoma has a low overall sensitivity. The lack of tissue architecture obtained by cytological needles decreases the diagnostic accuracy for diagnosis and subtyping of and relapsed mediastinal lymphomas. This study compares the sensitivity of EBUS-TBNA and endobronchial ultrasound-guided transbronchial mediastinal cryobiopsy (EBUS-TMC) for both initial lymphoma diagnosis and recurrent cases, analyses safety, and evaluates the number of mediastinoscopies that could potentially be avoided due to this novel technique.

Background: Thyroid nodules (TNs) are frequent and often benign. Accurately differentiating between benign and malignant nodules is crucial for proper management. This research aims to use ultrasonography to examine TNs and identify possible risk factors in order to improve patient outcomes and diagnostic accuracy.

Background: Metastases in the lateral pelvic lymph nodes or mesenteric lymph nodes represent distinct categories of mid-low rectal cancer. This study investigated the patterns of mesenteric and lateral pelvic lymph node metastases in mid-low rectal cancer; the survival benefit of postoperative treatment was also analysed in these groups.
Methods: This retrospective multicentre study included consecutive patients with mid-low rectal cancer who underwent total mesorectal excision with lateral pelvic lymph node dissection in three Chinese institutions between 2012 and 2020.

Hormonal status and lymphatic invasion are two important prognostic factors among cases of breast cancer. This study aims to assess and evaluate the hormonal receptor status and lymph node involvement among female breast cancer patients in Duhok city, Kurdistan region, Iraq. A retrospective cross-sectional study was conducted, involving 156 diagnosed cases of breast cancer who had undergone surgical treatment and laboratory investigations at Azadi Teaching Hospital and Duhok Private Hospital for 30 months.
