Purpose: During restaging after preoperative chemoradiotherapy (CRT), the assessment of lymph node (LN) metastasis is vital for selecting further treatment strategies. This study aimed to evaluate the impact of LN size to predict LN metastasis in rectal cancer patients after preoperative CRT.
Methods: A total of 30 consecutive patients who underwent preoperative CRT followed by curative resection of primary rectal cancer were selected as a study group (CRT group). As a control group (non-CRT group), 30 patients who underwent primary tumor resection were selected using a 1:1 case-match design. Matching criteria were gender, age, and clinical T stage. The size of each LN was measured from the surgical specimen. To clarify optimal cutoff values for node size according to the risk of detecting metastasis, receiving-operator characteristic (ROC) curves were generated.
Results: In the non-CRT group, 39/474 LNs were confirmed to have metastasis. In the CRT group, 29/422 LNs showed metastasis. The median size of metastatic LNs was 6.0 mm in CRT group, which was significantly larger than 4.0 mm in the non-CRT group (p = 0.006). The optimal cutoff value for determining metastasis in the CRT group was 4.5 mm, compared to 3.5 mm in the non-CRT group. The accuracy of the cutoff value was much higher in the CRT group (CRT vs. non-CRT, 77.9 vs. 59.9%).
Conclusions: LN size is a strong indicator for prediction of regional LN metastasis in rectal cancer patients after preoperative CRT, compared to those without CRT.

Outcomes and Toxicities After Treatment for Men Diagnosed With Localized Prostate Cancer in Low- and Middle-Income Countries: A Systematic Review and Meta-Analysis.

Department of Medical Imaging, Faculty of Allied Health Sciences, Kwame Nkrumah University of Science and Technology, Kumasi, Ghana.
Purpose: Current management for clinically localized prostate cancer in low- and middle-income countries (LMICs) includes surgery, external beam radiation therapy (EBRT), and brachytherapy either alone or in combination, with plus or minus hormone therapy. The toxicity profiles and oncological outcomes of these treatment modalities vary. This systematic review and meta-analysis aimed to determine the prevalence of treatment-related outcomes and toxicities for men diagnosed with localized prostate cancer in LMICs.

Medical Oncology Department, National Cancer Institute, Cairo University, Giza, Egypt.
Purpose: The role of adjuvant chemotherapy in rectal cancer patients downstaged to ypT0-2 N0 after neoadjuvant chemoradiotherapy (CRT), and surgery is still debated. This study investigates the impact of adjuvant chemotherapy on survival outcomes in this patient population.
Methods: This retrospective study analyzed hospital records of rectal cancer cases from Shefa Al Orman Cancer Hospital between January 2016 and December 2020, focusing on patients downstaged to ypT0-2 N0 after neoadjuvant CRT and surgery.

Department of Radiation Oncology, Tata Medical Center, Kolkata, India.
Background: Patients with locally advanced, surgically unresectable oral squamous cell cancers (SU-OSCC) are often treated with palliative intent. There is limited information on the outcomes of radical intent treatment with radiotherapy (RT) or chemoradiotherapy (CRT).
Methods: We retrospectively examined patients with Stage III/IV previously untreated SU-OSCC treated definitively from 2011 to 2021 in a single institution with RT or CRT with or without neoadjuvant chemotherapy (NACT).
Structural changes in the retina and choroid in patients with different degrees of myopia.

To observe the structural changes of retina and choroid in patients with different degrees of myopia. We recruited 219 subjects with different degrees of myopia for best corrected visual acuity, computer refraction, intraocular pressure, axial length (AL), optical coherence tomography (OCT) imaging, and other examinations. Central macular retinal thickness (CRT), subfoveal choroidal thickness (SFCT), nasal retinal thickness (NRT), temporal retinal thickness (TRT), nasal choroidal thickness (NCT) and temporal choroidal thickness (TCT) were measured by optical coherence tomography.
