Assessing the Need for Adjuvant Chemotherapy After Stereotactic Body Radiation Therapy in Early-stage Non-small Cell Lung Carcinoma.
Surgery remains the standard treatment for medically operable patients with early-stage non-small cell lung carcinoma (NSCLC). Following surgical resection, adjuvant chemotherapy is recommended for large tumors >4 cm. For unfit patients, stereotactic body radiation therapy (SBRT) has emerged as an excellent alternative to surgery. This study aims to assess patterns of recurrence and discuss the role of chemotherapy after SBRT for NSCLC.
We reviewed patients treated with SBRT for primary early-stage NSCLC between 2009 and 2015. Total target doses were between 50 and 60 Gy administered in three to eight fractions. All patients had a staging fluorodeoxyglucose (FDG) positron emission tomography (PET) integrated with computed tomography (CT) scan, and histologic confirmation was obtained whenever possible. Mediastinal staging was performed if lymph node involvement was suspected on CT or PET/CT. Survival outcomes were estimated using the Kaplan-Meier method.
Among the 559 early-stage NSCLC patients treated with SBRT, 121 patients were stage T2N0. The one-year and three-year overall survival rates were 88% and 70%, respectively, for patients with T2 disease, compared to 95% and 81%, respectively, for the T1 patients (p<0.05). The one-year and three-year local control rates were equal in both groups (98% and 91%, respectively). In T2 patients, 25 (21%) presented a relapse, among which 21 (84%) were nodal or distant. The median survival of T2N0 patients following a relapse was 11 months.
Lung SBRT provides high local control rates, even for larger tumors. When patients relapse, the majority of them do so at regional or distant sites. These results raise the question as to whether adjuvant treatment should be considered following SBRT for larger tumors

Exploring the Cervical Cancer Screening Experiences of Black Lesbian, Bisexual, and Queer Women: The Role of Patient-Provider Communication
Few studies have focused on the health and health care of U.S. black lesbian, bisexual, and queer (LBQ) women. To understand the facilitators of and barriers to cervical cancer screening in this population, focus group discussions were conducted in Boston and Cambridge, Massachusetts between November and December 2012. Using purposive sampling methods, the authors enrolled 18 black LBQ women who participated in one of four focus groups. Using thematic analysis, patient-provider communication was identified, which consisted of four sub-themes-health care provider communication style and demeanor; heteronormative provider assumptions; heterosexism, racism, and classism; and provider professional and sociodemographic background-as the most salient theme. Participants reported fears and experiences of multiple forms of discrimination and preferred receiving care from providers who were knowledgeable about same-sex sexual health and shared their life experiences at the intersection of gender, race/ethnicity, and sexual orientation. The cervical cancer screening experiences of black LBQ women would be improved by training all health care providers in same-sex sexual health, offering opportunities for clinicians to learn about the effects of various forms of discrimination on women's health care, and increasing the presence of LBQ women of color in health care settings
