PURPOSE: Metastatic colorectal cancer (mCRC) is a significant global health burden. This retrospective study compared the effectiveness of trifluridine/tipiracil (FTD/TPI), regorafenib, and chemotherapy rechallenge for third-line mCRC treatment. MATERIALS AND METHODS: We reviewed the medical records of 132 patients with mCRC treated with regorafenib, FTD/TPI, or a rechallenge with the initial chemotherapy regimen in a third-line setting from four different institutions. The primary end point was progression-free survival (PFS). Secondary end points were objective response rate and overall survival (OS) across the three treatment approaches. RESULTS: Twenty-nine patients received chemotherapy rechallenge, and 103 received FTD/TPI or regorafenib. Patients' characteristics were comparable, except for a lower number of left-sided primaries and KRAS wild-type tumors in the FTD/TPI-regorafenib group. The median PFS for the entire group was 3.0 months, and the median OS was 13.7 months. Chemotherapy rechallenge has resulted in a median PFS of 3.1 months and a median OS of 21.2 months, compared with 2.9 months (PFS) and 12.6 months (OS) for the FTD/TPI-regorafenib group. Multivariate analyses identified male sex and an Eastern Cooperative Oncology Group performance status (ECOG PS) of 0-1 as independent prognostic factors for better PFS, whereas chemotherapy rechallenge, localized stage at diagnosis, and an ECOG PS of 0-1 were significant prognostic factors for better OS. CONCLUSION: This study suggests that chemotherapy rechallenge may provide a survival benefit in the third-line treatment of mCRC. However, patient characteristics, such as sex and ECOG PS, should also be considered in treatment decisions. Further prospective studies are required to confirm our findings.

Management of early-stage non-small cell lung cancer (ES-NSCLC) has evolved over the last few years especially in terms of work-up and the use of systemic therapy. This consensus statement was developed to present updated guidelines for the management of this disease. Multidisciplinary team (MDT) of lung cancer experts convened to discuss a set of pertinent questions with importance relevance to the management of ES-NSCLC. ES-NSCLC includes stages I, II and resected stage III. The experts included consultants in chest imaging, thoracic surgery, radiation oncology, and medical oncology. Questions were discussed in virtual meetings and then a written manuscript with supporting evidence was drafted, reviewed, and approved by the team members. The Consensus Statement included 9 questions addressing work-up and management of ES-NSCLC. Background information and literature review were presented for each question followed by specific recommendations to address the questions by oncology providers. The Statement was endorsed by various oncology societies in the Gulf region. The Consensus Statement serves as a guide for thoracic MDT members in the management of ES-NSCLC. Adaptation of these to the local setting is dictated usually by available resources and expertise, however, all efforts should be excreted to provide the optimal care to all patients whenever possible.
Outcomes of Patients with Metastatic Colorectal Cancer Treated with Trifluridine/Tipiracil beyond the Second Line: A Multicenter Retrospective Study from Saudi Arabia: Background. The outcome of patients with refractory metastatic colorectal cancer (mCRC) treated with trifluridine/tipiracil (FTD/TPI) beyond the second-line has not been studied in Saudi Arabia. Therefore, this multicenter retrospective analysis was conducted to evaluate the efficacy of FTD/TPI. Methods. This multicenter retrospective analysis included five centers in Saudi Arabia. FTD/TPI was administered to all the patients beyond the oxaliplatin- and irinotecan-based chemotherapy regimens. The electronic medical records were reviewed, and progression-free survival (PFS) and overall survival (OS) were determined. Results. The study included 100 patients with a mean age of years. The overall response to FTD/TPI was 4%. The median PFS was 4 months (95% confidence interval (CI) 3.487–4.513), and the median OS was 11 months (95% CI, 9.226–12.771). In a Cox regression analysis of the independent predictors for PFS, advanced stage of the disease ( ; HR, 2.614; and CI, 1.102–7.524), presence of lymph node metastasis ( ; HR, 3.664; and 95% CI, 1.187–8.650), and >2 metastatic sites ( ; HR, 1.723; and 95% CI, 1.089–2.727) were independent factors predicting disease progression. The Cox regression analysis confirmed that years ( ; HR, 1.667; and 95%, 1.097–3.100), advanced disease stage ( ; HR, 1.283; and 95% CI, 1.035–2.940), prior use of adjuvant chemotherapy ( ; HR, 0.892; and 95% CI, 0.481–0.994), liver metastasis ( ; HR, 2.015; and 95% CI, 1.091–3.720), >2 metastatic sites ( ; HR, 1.248; and 95% CI, 1.036–1.846), development of neutropenia after receiving first cycle of FTD/TPI ( ; HR, 1.505; and 95% CI, 1.064–2.167), and increased number of FTD/TPI cycles ( ; HR, 0.769; and 95% CI, 0.664–0.891) were independent variables for OS. Conclusion. Treatment with FTD/TPI is feasible and effective in daily clinical practice in Saudi Arabian patients. The risk of progression increased with advanced disease stage, lymph node metastasis, bone metastasis, and metastasis to >2 sites.
Background: Primary squamous cell carcinoma of the breast (PSCCB) is a very rare malignancy of the breast. Pure squamous cell carcinoma of the breast can originate from skin adnexa, the nipple or the epithelium of deep-seated epidermoid cyst or squamous metaplasia on chronic inflammation background. Case Report: Our case is a 49-year-old female patient who presented with a highly suspicious lump in her left breast. Bilateral mammography and core biopsy were carried out. The core biopsy was revealed atypical cells and review inconclusive. Incisional biopsy was done and revealed squamous cell carcinoma of the breast (SCCB). Her metastatic work up at presentation was unremarkable. Left-side modified radical mastectomy was carried out. TNM staging was Stage IIa pT2N0M0 GIII, Estrogen receptors (ER) and Progesterone receptors were negative and HER2/Neu was negative as well (Triple negative). Pt had adjuvant chemotherapy and radiotherapy. Eight months later, she developed multiple brain metastasis as solitary site of metastasis, then after four months she developed hepatic and pulmonary deposits. Pt survived only 25 months since disease diagnosis. We report this case with relatively younger age to confirm that primary squamous cell carcinoma of the breast has special aggressive entity and this conjugant with few series. The treatment of primary SqCC of the breast does not differ from other common histological types of breast cancer so far. Conclusions: The prognosis of this disease is highly uncertain and the treatment options are unclear and controversial. There is inadequate literature and treatment guidelines. To our knowledge it is the first case to be reported from arab region with aggressive behavior and short survival period.
Mesenchymal-epithelial transition exon 14 (METex14) skipping mutations occur in about 3%-4% of patients with non-small cell lung cancer (NSCLC). This is an aggressive subtype associated with poor prognosis. METex14 skipping is a potentially targetable mutation. Targeted therapy is a promising treatment modality for patients with advanced/metastatic METex14-mutant NSCLC. Performing systematic molecular testing to detect the driver mutation is essential for initiating targeted therapy. However, there is a lack of guidelines on molecular testing for assessing the eligibility of patients for targeted therapy. Therefore, a multidisciplinary panel consisting of experts from the Middle East, Africa, and Russia convened via a virtual advisory board meeting to provide their insights on various molecular testing techniques for the diagnosis of METex14 skipping mutation, management of patients with targeted therapies, and developing consensus recommendations for improving the processes. The expert panel emphasized performing molecular testing and liquid biopsy before treatment initiation and tissue re-biopsy for patients with failed molecular testing. Liquid biopsy was recommended as complementary to tissue biopsy for disease monitoring and prognosis. Selective MET inhibitors were recommended as the first and subsequent lines of therapy. These consensus recommendations will facilitate the management of METex14 skipping NSCLC in routine practice and warrant optimum outcomes for these patients.
