Purpose: To assess the toxicity profile of erlotinib therapy combined with postoperative adjuvant radiation therapy in patients with advanced cutaneous squamous cell carcinoma.
Methods And Materials: This was a single-arm, prospective, phase 1 open-label study of erlotinib with radiation therapy to treat 15 patients with advanced cutaneous head-and-neck squamous cell carcinoma. Toxicity data were summarized, and survival was analyzed with the Kaplan-Meier method.
Results: The majority of patients were male (87%) and presented with T4 disease (93%). The most common toxicity attributed to erlotinib was a grade 2-3 dermatologic reaction occurring in 100% of the patients, followed by mucositis (87%). Diarrhea occurred in 20% of the patients. The 2-year recurrence rate was 26.7%, and mean time to cancer recurrence was 10.5 months. Two-year overall survival was 65%, and disease-free survival was 60%.
Conclusions: Erlotinib and radiation therapy had an acceptable toxicity profile in patients with advanced cutaneous squamous cell carcinoma. The disease-free survival in this cohort was comparable to that in historical controls.

Uganda's only radiotherapy center is a very busy facility treating about 210 patients daily on three linear accelerators making it sometimes hard to have machine time for pretreatment QAs. This study was aimed at validating an independent calculation software, ClearCalc (ICS) for second checks of the treatment planning system (TPS) calculations. The validation of ICS started with simple phantom test plans consisting of square, irregular, open and wedged fields designed in the TPS and measured in phantoms.

Purpose: To compare the effectiveness and safety of CT-guided iodine-125 seed brachytherapy in conjunction with chemotherapy against chemotherapy alone for the management of intermediate and advanced non-small cell lung cancer (NSCLC) lacking oncogenic driving genes.
Methods And Materials: Retrospective analysis was conducted on clinical data from 128 patients diagnosed with intermediate and advanced non-small cell lung cancer who received iodine-125 combined with chemotherapy or chemotherapy alone due to the absence of oncogenic driver gene mutations. The patients in two groups were compared at 6-month follow-up for objective remission rate (ORR), Disease control rate (DCR), local progression-free survival (LPFS), overall survival (OS), clinical symptom improvement, and adverse events.
