Elderly patients with good performance status should receive curative-intent surgery. Although hospital stay and tube dependence are longer, morbidity and mortality are comparable with younger patients.
Metastatic head and neck squamous cell carcinoma (HNSCC) has traditionally carried a dismal prognosis; however with advances in care, it has been shown that pulmonary metastasectomy is a viable therapeutic option in selected patients, palliating symptoms and improving survival. With the increasing incidence of human papilloma virus-related HNSCC and better availability of minimal access surgery, there is a need to better understand the role of pulmonary metastasectomy in the treatment of HNSCC. This article summarizes the literature on indications, results, surgical options and approaches, clinical dilemmas, and controversies associated with pulmonary metastasectomy in HNSCC, to identify suitable candidates and optimize outcomes.
Background: The treatment of primary CNS lymphoma (PCNSL) comprises high dose Methotrexate (HDMTX) based chemotherapy followed by whole brain radiotherapy(WBRT), the major drawback of which is long term neurotoxicity. We intended to assess the feasibility of response adapted WBRT in patients with PCNSL. Methods: We screened 35 patients & enrolled 24 patients with PCNSL in a phase II trial. They underwent 5 two-weekly cycles of MVP chemotherapy with HDMTX, Vincristine & Procarbazine. Rituximab was added in 16 patients as per their preference & affordability. Patients with complete response (CR) to induction chemotherapy were given reduced dose WBRT 23.4Gy/13fractions/2.5weeks while those with partial response (PR), stable or progressive disease(PD) were given standard dose WBRT 45Gy/25fractions/5 weeks. Thereafter 2 cycles of consolidation chemotherapy with Cytarabine was given. The primary endpoints of the study were assessment of response rate & progression free survival (PFS). The secondary endpoints were assessment of overall survival (OS), toxicity profile, serial changes in quality of life & neuropsychological parameters. Results: The median age at diagnosis was 50 years. Out of 20 patients who completed induction chemotherapy, 10(50%) achieved CR, 9(45%) had PR & 1 patient had PD. After a median follow-up period of 21.05 months, the median OS and PFS had not been reached. The actuarial rates of 3 year PFS & OS were 51% & 51.4% respectively. 4 patients in reduced dose WBRT arm had recurrence & 2 of them died of PD, whereas there was one recurrence and no cancer related death in standard dose WBRT arm. On univariate analysis of PFS, age60 years(p ¼ 0.004) & use of standard dose WBRT (p ¼ 0.047) led to significantly improved outcome. Serial neuropsychological assessments showed marked improvement in general cognition, verbal fluency & motor speed after induction chemotherapy & treatment completion. Conclusions: In patients with newly diagnosed PCNSL, reduced dose WBRT after CR to HDMTX based chemotherapy may lead to suboptimal clinical outcome due to higher risk of recurrence, progression & early death.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
