Delayed Hypersensitivity Reaction to Titanium-coated Polypropylene Mesh in Breast Reconstruction.

Breast implant reconstructions increasingly incorporate meshes like the synthetic nonresorbable titanium-coated polypropylene mesh commercialized as Tiloop (Pfm medical). We report the case of a 48-year-old woman, with a medical history of nickel allergy, who presented with an extensive erythematous eruption, a periprosthetic reaction, and an axillary node reaction, 18 months after a unilateral prophylactic mastectomy. We excluded infectious, sarcoidosis and carcinomatosis. The patient's medical history, the clinical evolution, and the particularly fast and complete healing after removal of the mesh were suggestive of an unusual allergic reaction to the titanium in the titanium-coated polypropylene mesh. Titanium allergies are very rare events, predominantly described in the dental and orthopedic fields. We also discussed the hypothesis of a tardive red breast syndrome related to a synthetic mesh, also mediated by immunological response as described recently in another case report.

Long-Term Follow-up of Immediate Latissimus Dorsi Flap Reconstruction After Neoadjuvant Chemotherapy and Radiotherapy for Invasive Breast Cancer.

BACKGROUND: The treatment sequence involving a mastectomy and immediate breast reconstruction (IBR) via the latissimus dorsi flap technique after chemotherapy and radiotherapy is not common. Our experience of this alternative to the standard treatment at our institute is reported herein. PATIENTS AND METHODS: This was a single-center, retrospective study. We enrolled patients who received this so-called "inverse" sequence for invasive, nonmetastatic breast cancer between 2009 and 2016. RESULTS: Fifty-two patients, aged between 24 and 65 years, with a mean body mass index of 24.5 underwent this treatment. Most involved T2 (59.6%, n = 32), multifocal (55.8%, n = 29) tumors, and 57.7% (n = 30) of the patients presented with axillary lymph node involvement. All patients had received sequential chemotherapy and 50 Gy of radiation. Pathological complete response (pCR) was found in 51.3% (n = 20), of cases in the traditional inverse sequence group, using Chevalier and Sataloff classifications (T and N pCR). Postoperatively, 1 patient required surgical revision because of a hematoma, 42 (80.8%) presented with lymphocele, 3 had impaired would healing, and 2 had more than 5 cm of skin necrosis on the front flap. Median follow-up was 61.9 months and the median time between diagnosis and surgery was 9.7 months. Three patients presented with metastases, 2 with local recurrence, and 1 patient died of cancer. No contralateral or lymph node recurrence was discovered. CONCLUSION: This treatment sequence, the feasibility of which was shown in this study, is an alternative for patients who want an IBR to avoid the time spent without one breast. This practice requires upstream multidisciplinary cooperation for optimal patient screening.

Pericarditis After Breast Implant Rupture: A Case Report.

A ruptured breast implant is usually asymptomatic and accidentally discovered during an imaging test. However, implant ruptures can cause isolated silicone granulomas and cases of severe systemic disease. We report the first case of a 39-year-old female patient with augmentation breast implants and myopericarditis secondary to implant rupture. Many etiologies of myopericarditis were explored, but none were selected with the exception of the rupture of the implant in the left breast. Magnetic resonance imaging showed a prosthetic rupture with capsular intrusion and formation of a silicone granuloma with inflammation of the pericardium on contact. Clinical and radiological improvement was observed in the short term after surgical removal of the implant. A review of the literature was conducted supporting the hypothesis of an autoimmune and inflammatory syndrome induced by an adjuvant.

Bilateral femur metastases in low-grade endometrial carcinoma.

Lower-limb bone metastases are uncommon in low-grade endometrial carcinoma, and are mostly located on the axial skeleton. Here, we present a rare case of bilateral femur metastases in low-grade endometrial carcinoma and performed a review of the current literature.

Completion surgery or not after concurrent chemoradiotherapy for locally advanced cervical cancer?

OBJECTIVES: The role of additional surgery in patients responding to radiation and chemotherapy for locally advanced cervical cancer is controversial. The goal of this study was to compare disease-free survival (DFS) and overall survival (OS) of two groups of patients, with or without additional surgery. STUDY DESIGN: One hundred and eleven patients with advanced cervical cancer who responded to chemoradiotherapy followed by brachytherapy were included in a retrospective, multicenter series. RESULTS: Of the patients who had completion surgery (Group 1), 22.4% (15/67) had recurrence compared with 36.4% (16/44) of those who did not have surgery (Group 2). The difference is statistically significant (p=0.01). The relative risk of disease progression or death was 0.41 (95% confidence interval 0.20-0.85) (p=0.01) in favor of completion surgery. After multivariate analysis, only age, pathology and initial tumor size remained significant (respectively p=0.003, p=0.001 and p=0.03). Among the locations of recurrence in Group 1, 46.7% were pelvic (7/15) compared with 56.2% in Group 2 (9/16). In Group 1, 16.4% (11/67) of the patients died of disease compared to 20.4% (9/44) in Group 2. Of these, 45.4% (5/11) in Group 1 died after pelvic recurrence as compared to 77.8% (7/9) in Group 2. CONCLUSION: Completion surgery does not improve OS but may improve DFS. There is no consensus regarding completion surgery in advanced cervical cancer with a good response to the standard treatment but we think it is safer to propose it.

Results of surgery after concurrent chemoradiotherapy in advanced cervical cancer: comparison of extended hysterectomy and extrafascial hysterectomy.

OBJECTIVES: The primary objective of this study was to compare disease-free survival (DFS) and overall survival (OS) of patients with and without completion surgery. The secondary objective was to compare DFS and OS of patients who had had systematic simple extrafascial hysterectomy or extended hysterectomy. The other objectives were to compare early and late complications with and without completion surgery and between the various surgical techniques. METHODS: One hundred seventy-one patients with advanced cervical cancer were included in a retrospective, multicenter series. RESULTS: The rate of pelvic control was 81.29% in our study after chemoradiotherapy, but histological residual cervical tumor persisted in nearly half of cases (49.71%). After a mean follow-up of 33 months, OS and DFS were not significantly higher in surgically treated patients, nor was the complication rate higher. Overall survival and DFS were not better after radical hysterectomy than after extrafascial hysterectomy. Statistically significant predictors of survival were clinical stage, tumor size, node extension, and residual tumor after chemoradiotherapy. CONCLUSION: There is no consensus regarding the maximal residual tumor volume after chemoradiotherapy suitable for surgery as there is no reliable imaging yet. Therefore, extrafascial hysterectomy with bilateral pelvic lymphadenectomy seems as a reasonable option if there are histological factors suggesting poor prognosis.
