Résumé

PURPOSE: To date, studies investigating the association between dairy consumption and breast cancer in women have produced conflicting results. As diet is an important, modifiable factor affecting cancer development, the aim of this study was to examine the association between dairy consumption and breast cancer risk. METHODS: PubMed, Embase, and Cochrane Library databases were searched with a priority for prospective cohort studies. Case-control studies were also considered in case of the absence of a cohort study. RESULTS: We analyzed 22 prospective cohort studies (1,566,940 participants) and five case-control studies (33,372 participants). High and modest dairy consumption (>600 and 400-600 g/day, respectively) significantly reduced the risk of breast cancer compared with low dairy consumption ( or =10 years (RR, 0.90; 95% CI, 0.81-0.99). Additionally, the highest level of dairy consumption among Asians was associated with a reduced risk of breast cancer (odds ratio, 0.74; 95% CI, 0.62-0.88). CONCLUSION: Dairy consumption was inversely associated with the risk of developing breast cancer and this effect was dependent on the dose, dairy-type, and time.

Résumé

Objective To discuss the design of pedicled thoracodorsal artery perforator flap (TDAP flap),and to evaluate the aesthetic results and donor-site complications for immediate partial breast reconstruction (IPBR) after breast conserving surgery (BCS) for breast cancer patients.Method Clinical data of 13 breast cancer cases treated with BCS + IPBR using TDAP flap from November 2004 to November 2010 were retrospectively analyzed.Perforators were identified with Doppler preoperatively in all patients.Results All perforators originated within a median distance of 8.0 cm ( range,7.5 to 9.5 cm) from axillary plica at the posterior line of axilla.Median area of the flaps was 6.0 × 8.0 cm ( range,5.0 × 7.0 cm to 8.0 × 10.0 cm).One flap was muscle-sparing,while a small muscle strip was left embedding the perforators in other twelve flaps to increase the reliability of the vascular pedicle.Postoperatively patients were followedup from 4 to 71 months.Median follow-up time was 41 months.Flap necrosis and seroma in the donor-site were not found in all patients.Aesthetic results were graded as excellent or good in 9 patients,fair in 3,and poor in one.Conclusions TDAP flap is a good choice for IPBR after BCS for breast cancer patients whether lesions in outer quadrants or inner quadrants,especially for those patients with excisional biopsy.Preoperative mini-Doppler is helpful for determining the precise location of the main perforators,and decreasing the risk of vessels injury.
