RESUMEN

OBJECTIVE: Clear cell carcinoma (CCC) of the uterus is a rare but aggressive histology for which the role of adjuvant therapy for stage I-II disease is unclear. Our study investigated outcomes and patterns of failure in these patients. METHODS: We found 64 cases of CCC, including 26 of pure CCC, 22 mixed with endometrioid adenocarcinoma, and 16 mixed with uterine papillary serous carcinoma. Adjuvant treatment was given to 55%. RESULTS: Median follow-up was 51.9 months. By Kaplan-Meier estimate, 5-year vaginal recurrence-free survival (RFS) was 91.3%, pelvic RFS was 92.6%, distant metastasis RFS was 81.6%, disease-free survival was 79.6%, and overall survival was 79.7%. Median time to recurrence was 20.7 months (range, 2 to 40.5 mo). Patients treated adjuvantly had higher proportion of stage II disease (40% vs. 6.9% observed, P=0.0031) and 20% (7/35) recurred. There were no significant differences in outcomes by histologic subtypes but numerically more recurrences with uterine papillary serous involvement. By univariate analysis, higher stage, presence of lymphovascular invasion, and lack of lymph node dissection were predictive of worse overall survival. Age 65 years and above was predictive of worse cancer-specific survival. Of 12 who progressed, only 1 was salvaged and 11 died of disease. Of progressors, 10 had documented distant metastasis. Median time from recurrence to death was 4.5 months (range, 0.2 to 21.2 mo). CONCLUSIONS: Given aggressive and often unsalvageable nature of recurrence, consideration of adjuvant treatment (including chemotherapy and radiation) is warranted for early-stage CCC, particularly for stage II or those with poor prognostic factors.

RESUMEN

BACKGROUND AND PURPOSE: Pre- and mid-radiotherapy FDG-PET metrics have been proposed as biomarkers of recurrence and survival in patients treated for stage III non-small cell lung cancer. We evaluated these metrics in patients treated with definitive radiation therapy (RT). We also evaluated outcomes after progression on mid-radiotherapy PET/CT. MATERIAL AND METHODS: Seventy-seven patients treated with RT with or without chemotherapy were included in this retrospective study. Primary tumor and involved nodes were delineated. PET metrics included metabolic tumor volume (MTV), total lesion glycolysis (TLG), and SUVmax. For mid-radiotherapy PET, both absolute value of these metrics and percentage decrease were analyzed. The influence of PET metrics on time to death, local recurrence, and regional/distant recurrence was assessed using Cox regression. RESULTS: 91% of patients had concurrent chemotherapy. Median follow-up was 14months. None of the PET metrics were associated with overall survival. Several were positively associated with local recurrence: pre-radiotherapy MTV, and mid-radiotherapy MTV and TLG (p=0.03-0.05). Ratio of mid- to pre-treatment SUVmax was associated with regional/distant recurrence (p=0.02). 5/77 mid-radiotherapy scans showed early out-of-field progression. All of these patients died. CONCLUSIONS: Several PET metrics were associated with risk of recurrence. Progression on mid-radiotherapy PET/CT was a poor prognostic factor.

RESUMEN

OBJECTIVE: Our aim was to examine underserved women's perceptions on mobile versus fixed mammography in Santa Clara, California through a focus group study. BACKGROUND:  Research has shown that medically underserved women have higher breast cancer mortality rates correlated with under-screening and a disproportional rate of late-stage diagnosis. The Community Health Partnership in Santa Clara County, California runs the Community Mammography Access Project (CMAP) that targets nearly 20,000 medically underserved women over the age of 40 in the county through the collaborative effort of an existing safety net of healthcare providers. However, little data exists on the advantages or disadvantages of mobile mammography units from the patient perspective.  METHODS:  We assessed underserved women's perspectives on mammography services in Santa Clara County through two focus groups from women screened at mobile or fixed site programs. Patients were recruited from both CMAP clinics and a county hospital, and focus group data were analyzed using content analysis. RESULTS:  We found that women from both the mobile and fixed sites shared similar motivating factors for getting a mammogram. Both groups recognized that screening was uncomfortable but necessary for good health and had positive feedback about their personal physicians. However, mobile participants, in particular, appreciated the atmosphere of mobile screening, reported shorter wait times, and remarked on the good communication from the clinic staff and empathetic treatment they received. However, mobile participants also expressed concern about the quality of films at mobile sites due to delayed initial reading of the films.  CONCLUSIONS:  Mobile mammography offers a unique opportunity for women of underserved populations to access high satisfaction screenings, and it encourages a model similar to CMAP in other underserved areas. However, emphasis should be placed on providing a warm and welcoming environment for patients and ensuring the quality of mammography images.

RESUMEN

UNLABELLED: Many patients with lung tumors have tumors too large for stereotactic ablative radiotherapy and comorbidities precluding concurrent chemotherapy. We report the outcomes of 29 patients treated with hypofractionated radiotherapy (RT) to 60 to 66 Gy in 3-Gy fractions. We also report an exploratory analysis of the prognostic value of the pre- and mid-RT positron emission tomography-computed tomography. INTRODUCTION: Modestly hypofractionated radiation therapy (HypoRT; 60-66 Gy in 3-Gy fractions) allows patients with locally advanced thoracic tumors and poor performance status to complete treatment within a shorter period without concurrent chemotherapy. We evaluated the outcomes and imaging prognostic factors of HypoRT. MATERIALS AND METHODS: We retrospectively reviewed the data from all patients with primary and metastatic intrathoracic tumors treated with HypoRT from 2006 to 2012. We analyzed the survival and toxicity outcomes, including overall survival (OS), progression-free survival (PFS), local recurrence (LR), and distant metastasis. We also evaluated the following tumor metrics in an exploratory analysis: gross tumor volume (GTV), maximum standardized uptake value (SUVMax), and metabolic tumor volume using a threshold of ≥ 50% of the SUVMax (MTV50%) or the maximum gradient of fluorine-18 fluorodeoxyglucose uptake (MTVEdge). We assessed the association of these metrics and their changes from before to mid-RT using positron emission tomography-computed tomography (PET-CT) with OS and PFS. RESULTS: We identified 29 patients, all with pre-RT and 20 with mid-RT PET-CT scans. The median follow-up period was 15 months. The 2-year overall and non-small-cell lung cancer-only rate for OS, PFS, and LR, was 59% and 59%, 52% and 41%, and 27% and 32%, respectively. No grade ≥ 3 toxicities developed. The median decrease in GTV, SUVMax, and MTVEdge was 11%, 24%, and 18%, respectively. Inferior OS was associated with a larger pre-RT MTVEdge (P = .005) and pre-RT MTV50% (P = .007). Inferior PFS was associated with a larger mid-RT SUVMax (P = .003). CONCLUSION: These findings add to the growing body of data demonstrating promising outcomes and limited toxicity with HypoRT. The pre- and mid-RT PET-CT metrics could be useful for prognostic stratification in future clinical trials.

RESUMEN

OBJECTIVE: To compare the efficacy and tolerance of adjuvant chemotherapy and radiotherapy delivered in sequential (chemotherapy followed by radiation) versus "sandwich" fashion (chemotherapy, interval radiation, and remaining chemotherapy) after surgery in patients with FIGO stage III uterine endometrioid adenocarcinoma. METHODS: From 2004 to 2011, we identified 51 patients treated at our institution fitting the above criteria. All patients received surgical staging followed by adjuvant chemoradiation (external-beam radiation therapy (EBRT) with or without high-dose rate (HDR) vaginal brachytherapy (VB)). Of these, 73% and 27% of patients received their adjuvant therapy in sequential and sandwich fashion, respectively. RESULTS: There were no significant differences in clinical or pathologic factors between patients treated with either regimen. Thirty-nine (76%) patients had stage IIIC disease. The majority of patients received 6 cycles of paclitaxel with carboplatin or cisplatin. Median EBRT dose was 45 Gy and 54% of patients received HDR VB boost (median dose 21 Gy). There were no significant differences in the estimated 5-year overall survival, local progression-free survival, and distant metastasis-free survival between the sequential and sandwich groups: 87% vs. 77% (p=0.37), 89% vs. 100% (p=0.21), and 78% vs. 85% (p=0.79), respectively. No grade 3-4 genitourinary or gastrointestinal toxicities were reported in either group. There was a trend towards higher incidence of grade 3-4 hematologic toxicity in the sandwich group. CONCLUSION: Adjuvant chemoradiation for FIGO stage III endometrioid uterine cancer given in either sequential or sandwich fashion appears to offer equally excellent early clinical outcomes and acceptably low toxicity.

RESUMEN

CONTEXT: Glioblastoma multiforme (GBM) is an aggressive neoplasm, with controversy regarding treatment in elderly patients. OBJECTIVE: To review outcomes of elderly patients aged ≥ 65 with newly diagnosed GBM treated with concurrent temozolomide and either standard-course radiotherapy (SRT) or abbreviated-course radiotherapy (ART). DESIGN: Retrospective review from 2003 to 2012. MAIN OUTCOME MEASURE: Survival, comparing treatment regimens. One hundred patients received SRT (median dose = 60 Gy), and 29 received ART (median dose = 35 Gy). O6- methylguanine-DNA methyltransferase (MGMT) status was available for 26 SRT and 13 ART recipients. RESULTS: Median age was 70 years. Median follow-up was 11 months. At analysis, 3 patients were alive. Multivariate analysis of the entire cohort found SRT (hazard ratio [HR] = 0.421, p = 0.0001), Karnofsky Performance Score of 70 or higher (HR = 1.894, p = 0.0031), and more extensive surgery (HR = 0.466, p = 0.0023) were associated with longer survival time, but age was not. Median time to death with SRT was 13 months versus 5.4 months with ART, but the latter had worse prognostic factors, including lower Karnofsky Performance Scores, fewer gross total resections, and higher recursive partitioning analysis class. Recipients of SRT with methylated MGMT promoter had a trend toward longer survival compared with unmethylated MGMT (p = 0.06), but ART recipients had shorter survival with MGMT methylation (p = 0.02). CONCLUSION: Elderly patients with multiple poor prognostic factors given ART had short survival times. Relative to other variables, MGMT status may not predict outcome for these patients.

RESUMEN

OBJECTIVE: To investigate clinical outcomes of stage IA uterine papillary serous (UPSC) and clear cell carcinoma (CC) arising from or associated with a polyp. METHODS: From 1995 to 2011, we identified 51 cases of stage IA UPSC (67%), CC (8%) or mixed histology (26%) endometrial cancer. Of these, 32 had disease confined to polyp (seven with no residual disease after hysterectomy), 14 had surface spread, 1 had myometrial invasion (MMI) and 4 had both. The majority of patients did not receive adjuvant therapy (80%). Patients given adjuvant treatment (either platinum-based chemotherapy alone, radiation alone, or a combination of the two) had incomplete staging or abnormal cytology. RESULTS: At mean follow-up of 58.3 months, only 4 patients had progressed, via pelvic adenopathy, carcinomatosis or both. There were no vaginal cuff recurrences. Kaplan-Meier 5 year estimates were pelvic control of 92.1%, disease-free survival 93% and OS 80.6%. Only 9% (3/32) of cases confined to polyp progressed. One responded to salvage chemoradiation, but two died despite salvage. Only 5% (1/19) of cases with surface and MMI progressed. On univariate analysis, only MMI and abnormal/positive cytology were significantly associated with increased pelvic recurrence (MMI p=0.0059, cytology p=0.0036) and worse DFS (MMI p=0.0018, cytology p=0.0054). Two patients given adjuvant treatment developed new gynecologic malignancies. CONCLUSION: In our study, patients with limited UPSC/CC disease involving a polyp who have complete workup did well without adjuvant therapy, with recurrence rates similar to UPSC/CC stage IA disease. Late and extensive pelvic relapses may occur in the few who do relapse.
