RESUMEN

BACKGROUND: Free flaps have a well-established role in breast reconstruction after mastectomy; however, their role in partial breast reconstruction remains poorly defined. We reviewed our experience with partial breast reconstruction to better understand indications for free tissue transfer. METHODS: A retrospective review was performed of all patients undergoing partial breast reconstruction at our center between February 2009 and October 2015. We evaluated the characteristics of patients who underwent volume displacement procedures versus volume replacement procedures and free versus pedicled flap reconstruction. RESULTS: There were 78 partial breast reconstructions, with 52 reductions/tissue rearrangements (displacement group) and 26 flaps (replacement group). Bra cup size and body mass index (BMI) were significantly smaller in the replacement group. Fifteen pedicled and 11 free flaps were performed. Most pedicled flaps (80.0%) were used for lateral or upper pole defects. Most free flaps (72.7%) were used for medial and inferior defects or when there was inadequate donor tissue for a pedicled flap. Complications included hematoma, cellulitis, and one aborted pedicled flap. CONCLUSION: Free and pedicled flaps are useful for partial breast reconstruction, particularly in breast cancer patients with small breasts undergoing breast-conserving treatment (BCT). Flap selection depends on defect size, location, and donor tissue availability. Medial defects are difficult to reconstruct using pedicled flaps due to arc of rotation and intervening breast tissue. Free tissue transfer can overcome these obstacles. Confirming negative margins before flap reconstruction ensures harvest of adequate volume and avoids later re-operation. Judicious use of free flaps for oncoplastic reconstruction expands the possibility for breast conservation.

RESUMEN

Few studies have examined cancer-related risk factors in relation to SES across the lifecourse in low to middle income countries. This analysis focuses on adult women in India, China, Mexico, Russia and South Africa, and examines the association between individual, parental and lifecourse SES with smoking, alcohol, BMI, nutrition and physical activity. Data on 22,283 women aged 18 years and older were obtained from the 2007 WHO Study on Global Aging and Adult Health (SAGE). Overall, 34% of women had no formal education, 73% had mothers with no formal education and 73% of women had low lifecourse SES. Low SES women were almost four times more likely to exceed alcohol use guidelines (OR: 3.86, 95% CI: 1.23-12.10), and 68% more likely to smoke (OR: 1.68, 95% CI: 1.01-2.80) compared with higher SES. Women with low SES mothers and fathers were more likely to have poor nutrition (Mothers OR: 1.59, 95% CI: 1.17-2.16; Fathers OR: 1.33, 95% CI: 1.11-1.59) and more likely to smoke (Mothers OR: 1.46, 95% CI: 1.15-1.87; Fathers OR: 2.17, 95% CI: 1.80-2.63) compared with those with high SES parents. Women with stable low lifecourse SES were more likely to smoke (OR: 2.55, 95% CI: 1.47-4.43), while those with declining lifecourse SES were more likely to exceed alcohol use guidelines (OR: 3.63, 95% CI: 1.07-12.34). Cancer-related risk factors varied significantly by lifecourse SES, suggesting that cancer prevention strategies will need to be tailored to specific sub-groups in order to be most effective.

RESUMEN

Nodal marginal zone lymphoma (NMZL) is a rare non-Hodgkin B-cell lymphoma that has historically been difficult to define, though is now formally recognized by the World Health Organization Classification. To better characterize the clinical outcomes of patients with NMZL, we reviewed a sequential cohort of 187 patients with NMZL to describe baseline characteristics, survival outcomes, and time-to-event data. Initial management strategies were classified into five categories: observation, radiation, anti-CD20 monoclonal antibody therapy, chemoimmunotherapy, or other. Baseline Follicular Lymphoma International Prognostic Index scores were calculated to evaluate prognosis. A total of 187 patients were analyzed. The five-year overall survival was 91% (95% confidence interval [CI], 87-95), with a median follow-up time of 71 months (range, 8-253) among survivors. A total of 139 patients received active treatment at any point, with a median follow-up time of 56 months (range, 13-253) among survivors who were never treated. The probability of remaining untreated at five years was 25% (95% CI, 19-33). For those initially observed, the median time to active treatment was 72 months (95% CI, 49-not reached). For those who received at least one active treatment, the cumulative incidence of receiving a second active treatment at 60 months was 37%. Transformation to large B-cell lymphoma was rare, with a cumulative incidence of 15% at 10 years. In summary, our series is a large cohort of uniformly diagnosed NMZL with detailed analyses of survival and time to event analyses. We showed that NMZL commonly presents as an indolent lymphoma for which initial observation is often a reasonable strategy.

RESUMEN

Between 1998 and 2009, a total of 295 patients (median age 58, 53% females) with newly diagnosed early-stage follicular lymphoma (FL) were managed at Memorial Sloan Kettering Cancer Center. Approximately half of patients (137, 46%) underwent initial observation and half (158, 54%) immediate treatment: radiation alone (n = 108), systemic treatment alone (n = 29), or combined modality treatment (n = 21). Median follow-up was 8.4 years (range 0.3-17.2), and 10-year overall survival (OS) was 87.2%. OS was similar between initially-observed and immediately-treated patients (hazard ratio [HR]: 1.25, 95% CI: 0.67-2.36, p = 0.49). For patients receiving radiation alone, 5-year OS was 98.0%. Patients selected for systemic therapy alone had high-risk baseline features and had shorter OS than patients treated with radiation alone (HR 3.38, 95% CI 1.29-8.86, p = 0.01). Combined modality treatment did not yield superior survival compared with radiation alone (P > 0.05) but was associated with better progression-free survival (HR 0.36, 95% CI 0.14-0.90, p = 0.03). The rate of transformation increased steadily over time and was 4.2% at 5 years and 10.8% at 10 years. This modern-era analysis rationalized the role of initial observation in patients with early-stage FL although patients receiving radiation therapy also demonstrate excellent outcome.

RESUMEN

BACKGROUND: Side effects associated with use of postoperative narcotics for pain control can delay recovery after abdominally based microsurgical breast reconstruction. The authors evaluated a nonnarcotic pain control regimen in conjunction with bilateral transversus abdominis plane blocks on facilitating early hospital discharge. METHODS: A retrospective analysis was performed of consecutive patients who underwent breast reconstruction using abdominally based free flaps, with or without being included in a nonnarcotic protocol using intraoperative transversus abdominis plane blockade. During this period, the use of locoregional analgesia evolved from none (control), to continuous bupivacaine infusion transversus abdominis plane and catheters, to single-dose transversus abdominis plane blockade with liposomal bupivacaine solution. Demographic factors, length of stay, inpatient opioid consumption, and complications were reported for all three groups. RESULTS: One hundred twenty-eight consecutive patients (182 flaps) were identified. Forty patients (62 flaps) were in the infusion-liposomal bupivacaine group, 48 (66 flaps) were in the single-dose blockade-catheter group, and 40 (54 flaps) were in the control group. The infusion-liposomal bupivacaine patients had a significantly shorter hospital stay compared with the single-dose blockade-catheter group (2.65 ± 0.66 versus 3.52 ± 0.92 days; p < 0.0001) and the control group (2.65 ± 0.66 versus 4.05 ± 1.26 days; p < 0.0001). There was no significant difference in flap loss or major complications among groups. CONCLUSIONS: When used as part of a nonnarcotic postoperative pain regimen, transversus abdominis plane blocks performed with single injections of liposomal bupivacaine help facilitate early hospital discharge after abdominally based microsurgical breast reconstruction. A trend toward consistent discharge by postoperative day 2 was seen. This could result in significant cost savings for health care systems. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

RESUMEN

BACKGROUND: Cancer prevention guidelines have been developed to improve knowledge and adherence to modifiable cancer risk factors. The implementation of these guidelines has largely been studied in North American and European populations. The aim of this study was to examine the association between health care access and adherence to the World Cancer Research Fund/American Institute for Cancer Research (WCRF/AICR) cancer prevention guidelines in South Africa, where the cancer incidence is rising. METHODS: Data from the 2003 South Africa World Health Survey was used to assess adherence to WCRF/AICR cancer prevention guidelines on alcohol, body mass index, nutrition, physical activity and smoking. Health care affordability, availability, accessibility, accommodation and acceptability in the past 12 months were assessed via self-report. RESULTS: Residing in a high socio-economic status household (affordability), visiting a non-governmental health care facility (availability), perception of health care provider skills as adequate (accommodation) and lack of perception of worse treatment based on social class (acceptability) were each associated with higher levels of adherence to the WCRF/AICR guidelines. CONCLUSIONS: In South Africa, better access to health care is associated with better patient adherence to cancer prevention guidelines. Future studies and efforts can focus on improving access to quality health care in this population.
