The pedicled omentoplasty and split skin graft (POSSG) for reconstruction of large chest wall defects. A validity study of 34 patients

The aim of this study was to evaluate retrospectively the results of pedicled omentoplasty and split skin graft (POSSG) in reconstructing (full thickness) chest wall defects, and to define its role as a palliative procedure for local symptom control. Thirty-four patients with recurrent breast cancer (n = 25), radiation-induced necrosis (n = 5) or sarcoma (n = 4) of the chest wall were selected for the study. All patients underwent curative or palliative chest wall resection with reconstruction by pedicled omentoplasty and split skin graft (POSSG), between 1986 and 1994. Reconstructive outcome, complications, local tumour and symptom control following surgery was measured. The most common complication was shown to be partial necrosis of the omental flap (35%), followed by respiratory problems (26%), facial hernia (26%) and thoracic wound problems (15%), which were mostly treated in a conservative way (68%). The 3-year local tumour-free interval after POSSG in patients curatively treated for breast cancer is 16%. Seventy per cent of the patients who underwent palliative resection had longstanding relief of local pain, bleeding or foetor due to local tumour growth. It can be concluded that large (full thickness) chest wall defects after resection of local recurrence, primary malignancy or osteoradionecrosis of the chest wall can successfully be reconstructed by POSSG. Chest wall resection in patients treated with palliative intention is effective in local symptom control

High relapse-free survival after preoperative and intraoperative radiotherapy and resection for sulcus superior tumors

STUDY OBJECTIVES: Relapse-free survival in patients with sulcus superior tumors. DESIGN: Prospective registration study. SETTING: Department of surgical oncology of a university hospital. PATIENTS: Twenty-one patients treated with preoperative radiotherapy (46 Gy), lobectomy and chest-wall resection, and intraoperative radiotherapy (10 Gy). RESULTS: After a median follow-up of 18 months, 18 patients (85%) were free from locoregional relapse, while 8 patients were still alive. CONCLUSIONS: The results show that this protocol can achieve excellent local tumor control and can even be used for palliative treatment

Fifty tumor necrosis factor-based isolated limb perfusions for limb salvage in patients older than 75 years with limb-threatening soft tissue sarcomas and other extremity tumors

BACKGROUND: Isolated limb perfusion (ILP) with tumor necrosis factor (TNF) and melphalan is highly effective in treating limb-threatening soft tissue sarcoma (STS) and other bulky tumors. Because of fear of TNF-associated toxicity, ILP with TNF is not offered to older patients in some cancer centers, although especially in older patients, every attempt to avoid an amputation that may end their independence must be considered. METHODS: Out of 306 TNF-based ILPs, 50 ILPs were performed for limb salvage in 43 patients >75 years old (range, 75-91 years): 29 STS and 14 melanoma patients. RESULTS: In the STS patients, a response rate of 76% and a limb-salvage rate of 76% were achieved; in the melanoma patients, a 100% response rate and a 93% limb-salvage rate were achieved. Local toxicity was mild. The three postoperative deaths that occurred in the total series of 306 TNF-based ILPs in Rotterdam (75 years old after leakage-free perfusions and were not related to TNF but to extremely high-risk profiles in these three patients. CONCLUSIONS: Older patients should not be withheld a TNF-based ILP for limb salvage, because the procedure is safe and highly effective in these patients

The composition of serous fluid after axillary dissection

Objective: To analyse the composition of the serous fluid formed after axillary dissection Design: Descriptive study Setting: University hospital and teaching hospital, The Netherlands Subjects: 16 patients whose axillas were dissected as part of a modified radical mastectomy for stage I or II breast cancer. Main outcome measures: Chemical and cellular composition of axillary drainage fluid on the first, fifth, and tenth postoperative days compared with the same constituents in blood and with reported data on the composition of peripheral lymph. Results and conclusion: On the first postoperative day the drainage fluid contained blood contents and a high concentration of creatine phosphokinase (CPK). After day one it changed to a peripheral lymph-like fluid but containing different cells, more protein, and no fibrinogen, making coagulation impossible. The reduction in the fluid production must be caused by other wound healing processes, such as formation of scars and connective tissue

One hundred consecutive isolated limb perfusions with TNF-alpha and melphalan in melanoma patients with multiple in-transit metastases

OBJECTIVE: The aim of this study is to describe the experience with 100 TNF-based ILP for locally advanced melanoma and to determine prognostic factors for response, time to local progression, and survival. METHODS: One hundred TNF-based ILPs were performed between 1991 and 2003 in 87 patients for whom local control by surgery of in-transit melanoma metastases was impossible. In total, 62 iliac, 33 femoral, and 5 axillary ILPs were performed in mild hyperthermic conditions with 2 to 4 mg of TNF and 10 to 13 mg of melphalan per liter of limb volume. RESULTS: Overall response was 95%, with 69% complete response, 26% partial response, and 5% no change. Complete response rate differed significantly for patients with IIIA disease versus IIIAB and IV. Local and systemic toxicity was mild to moderate in almost all cases, with no treatment-related death and one treatment-related amputation. Five-year overall survival was 32%; local progression occurred in 55% after a median of 16 months. In complete response patients, 5-year survival was 42% with local progression in 52% at a median of 22 months. Response rate and survival were significantly influenced by stage of disease; (local progression free) survival was influenced by response rate. CONCLUSIONS: TNF-based ILP results in excellent response rates in this patient population with unfavorable characteristics. Response on ILP predicts outcome in patients and reflects aggressiveness of the tumor

Mastectomy by inverted drip incision and immediate reconstruction: data from 510 cases

BACKGROUND: Immediate reconstruction of the breast can be performed in selected cases after mastectomy for breast cancer or after prophylactic mastectomy in patients with a high risk of developing breast cancer. Despite the frequency with which these procedures are performed, data from large series of subpectoral implantation of silicone prostheses in combination with a skin-saving approach are lacking. METHODS: In this retrospective study, data on complications and late surgical interventions in 356 patients who underwent 510 mastectomies with an inverted drip incision and immediate reconstruction (MIDIIR) were analyzed to determine potential prognostic factors of early complications. RESULTS: In 82% of the MIDIIRs, the postoperative course was uneventful. In 18%, the complications were infection (32 cases), necrosis of the skin flap (29 cases), bleeding (31 cases), and protrusion of the prosthesis (20 cases), resulting in surgery in 9, 12, 15, and 20 cases, respectively. At the end of the follow-up period, 30 (6%) prostheses were definitively removed. Age, size of the prostheses, radiotherapy, previous lumpectomy, and indication for mastectomy were not significant factors for the prognosis of early complications. CONCLUSIONS: With the right technique and indications, MIDIIR is a very safe procedure and should be one of the surgical treatments that can be offered in the overall management of patients with, or at high risk for, breast cancer

Global Retinoblastoma Presentation and Analysis by National Income Level

Importance: Early diagnosis of retinoblastoma, the most common intraocular cancer, can save both a child's life and vision. However, anecdotal evidence suggests that many children across the world are diagnosed late. To our knowledge, the clinical presentation of retinoblastoma has never been assessed on a global scale. Objectives: To report the retinoblastoma stage at diagnosis in patients across the world during a single year, to investigate associations between clinical variables and national income level, and to investigate risk factors for advanced disease at diagnosis. Design, Setting, and Participants: A total of 278 retinoblastoma treatment centers were recruited from June 2017 through December 2018 to participate in a cross-sectional analysis of treatment-naive patients with retinoblastoma who were diagnosed in 2017. Main Outcomes and Measures: Age at presentation, proportion of familial history of retinoblastoma, and tumor stage and metastasis. Results: The cohort included 4351 new patients from 153 countries; the median age at diagnosis was 30.5 (interquartile range, 18.3-45.9) months, and 1976 patients (45.4) were female. Most patients (n = 3685 84.7%) were from low-and middle-income countries (LMICs). Globally, the most common indication for referral was leukocoria (n = 2638 62.8%), followed by strabismus (n = 429 10.2%) and proptosis (n = 309 7.4%). Patients from high-income countries (HICs) were diagnosed at a median age of 14.1 months, with 656 of 666 (98.5%) patients having intraocular retinoblastoma and 2 (0.3%) having metastasis. Patients from low-income countries were diagnosed at a median age of 30.5 months, with 256 of 521 (49.1%) having extraocular retinoblastoma and 94 of 498 (18.9%) having metastasis. Lower national income level was associated with older presentation age, higher proportion of locally advanced disease and distant metastasis, and smaller proportion of familial history of retinoblastoma. Advanced disease at diagnosis was more common in LMICs even after adjusting for age (odds ratio for low-income countries vs upper-middle-income countries and HICs, 17.92 95% CI, 12.94-24.80, and for lower-middle-income countries vs upper-middle-income countries and HICs, 5.74 95% CI, 4.30-7.68). Conclusions and Relevance: This study is estimated to have included more than half of all new retinoblastoma cases worldwide in 2017. Children from LMICs, where the main global retinoblastoma burden lies, presented at an older age with more advanced disease and demonstrated a smaller proportion of familial history of retinoblastoma, likely because many do not reach a childbearing age. Given that retinoblastoma is curable, these data are concerning and mandate intervention at national and international levels. Further studies are needed to investigate factors, other than age at presentation, that may be associated with advanced disease in LMICs. © 2020 American Medical Association. All rights reserved
