ObjectiveTo explore the effectiveness of the modified designed bilobed latissimus dorsi myocutaneous flap in chest wall reconstruction of locally advanced breast cancer (LABC) patients.MethodsBetween January 2016 and June 2019, 64 unilateral LABC patients were admitted. All patients were female with an average age of 41.3 years (range, 34-50 years). The disease duration ranged from 6 to 32 months (mean, 12.3 months). The diameter of primary tumor ranged from 4.8 to 14.2 cm (mean, 8.59 cm). The size of chest wall defect ranged from 16 cm×15 cm to 20 cm×20 cm after modified radical mastectomy/radical mastectomy. All defects were reconstructed with the modified designed bilobed latissimus dorsi myocutaneous flaps, including 34 cases with antegrade method and 30 cases with retrograde method. The size of skin paddle ranged from 13 cm×5 cm to 17 cm×6 cm. All the donor sites were closed directly.ResultsIn antegrade group, 2 flaps (5.8%, 2/34) showed partial necrosis; in retrograde group, 6 flaps (20%, 6/30) showed partial necrosis, 5 donor sites (16.7%, 5/30) showed partial necrosis; and all of them healed after dressing treatment. The other flaps survived successfully and incisions in donor sites healed by first intention. There was no significant difference in the incidence of partial necrosis between antegrade and retrograde groups (χ2=2.904, P=0.091). The difference in delayed healing rate of donor site between the two groups was significant (P=0.013). The patients were followed up 15-30 months, with an average of 23.1 months. The appearance and texture of the flaps were satisfactory, and only linear scar left in the donor site. No local recurrence was found in all patients. Four patients died of distant metastasis, including 2 cases of liver metastasis, 1 case of brain metastasis, and 1 case of lung metastasis. The average survival time was 22.6 months (range, 20-28 months).ConclusionThe modified designed bilobed latissimus dorsi myocutaneous flap can repair chest wall defect after LABC surgery. Antegrade design of the flap can ensure the blood supply of the flap and reduce the tension of the donor site, decrease the incidence of complications.
Patients with locally advanced thyroid cancer often face challenges in achieving radical surgery during initial diagnosis. This has become a significant hurdle in the treatment of thyroid cancer. With the continuous development of systemic therapy for thyroid cancer, several studies have demonstrated that neoadjuvant therapy can shrink tumors in some patients, thereby increasing the chances of complete resection and improving prognosis. Targeted therapy plays a crucial role as a core component of neoadjuvant treatment. Simultaneously, the potential efficacy of immunotherapy has gained attention, showing promising prospects. We aim to summarize the research progress and existing issues regarding neoadjuvant therapy for locally advanced thyroid cancer. We look forward to more high-quality clinical studies providing robust evidence for neoadjuvant therapy in locally advanced thyroid cancer, expanding the breadth of treatment options.
Surgery is the preferred treatment for resectable esophageal cancer, but in locally advanced esophageal cancer, the effect of surgery alone is not ideal, so surgery-based comprehensive treatment is the best option. Neoadjuvant therapy has become a standard treatment in the treatment of locally advanced resectable esophageal cancer. Neoadjuvant therapy includes neoadjuvant chemotherapy, radiochemotherapy, immunotherapy, targeted therapy, etc. With the significant efficacy and acceptable toxicity of immunotherapy in the first-line and second-line treatment of advanced esophageal cancer, neoadjuvant immunotherapy has become a research hotspot of locally advanced resectable esophageal cancer. This article reviews the latest research progress and some limitations of neoadjuvant immunotherapy in locally advanced resectable esophageal cancer.
Lung cancer is the malignant tumor with the highest incidence and mortality rate in China, which seriously threatens the life and health of Chinese people. Locally advanced unresectable non-small cell lung cancer is characterized by high heterogeneity and poor prognosis, and durvalumab consolidation therapy after concurrent chemoradiotherapy is the main treatment modality. In recent years, advances in targeted therapies and immunotherapy have changed the treatment landscape of lung cancer. A portion of locally advanced or advanced non-small cell lung cancer that was initially unresectable is down-staged and converts to surgically operable radical resection after comprehensive treatment, and this surgical treatment strategy is called conversion surgery. With the progress of comprehensive treatment modalities, it may occupy an increasing proportion in thoracic surgery in the future. This article reviews the treatment modality and conversion surgery for locally advanced unresectable non-small cell lung cancer.
Objective We searched and reviewed medical evidence to find the guide of treatment for local advanced nasopharyngeal carcinoma. Methods Firstly, we put forward clinical questions. Secondly, we searched medical evidence from Medline (1985-2002), Embase (1984-2000), Cochrane library (2002.1) and ACP. And then we reviewed the results. The key words we used were "nasopharyngeal carcinoma, chemotherapy and radiotherapy randomized" and "meta analysis or randomized control trial". Results Through searching, we got 17 papers including 1 systematic review and 16 randomized control trials, in which there were 8 prospective randomized phase Ⅲ trials. Most of these trials concluded that combination chemo-radiotherapy were better than radiotherapy alone. We think these results were suitable for our patient’treatment decision. Conclusion To treat our patients,we choosed the method of the mutimodality of squeitial neoadjuvant chemotherapy, concurrent chemo-radiotherapy and adjuvant chemotherapy with the drug doses down-adjusted.
ObjectiveTo systematically review the effectiveness and safety of taxanes combined with cisplatin and fluorouracil (TFP) versus cisplatin and fluorouracil (FP) for locally advanced head and neck squamous cell carcinoma. MethodsDatabases such as The Cochrane Library (Issue 1, 2013), PubMed, EMbase, Web of Science, CBM, CNKI, VIP and WanFang Data were electronically searched to collect randomized controlled trials (RCTs) about taxanes combined with cisplatin and fluorouracil in the treatment of locally advanced head and neck squamous cell carcinoma from the date of their establishment to April 1st, 2013. Two reviewers independently screened studies according to the inclusion and exclusion criteria, extracted data and evaluated the methodological quality of included studies. Then meta-analysis was performed using RevMan 5.2 software. ResultsA total of 7 RCTs involving 2 088 patients were included. The TFP group included 1 051 cases, while the FP group included 1 037 cases. The results of meta-analyses showed that, there were significant differences between the two groups in the 1-year, 2-year, and 3-year overall survival rates (RR=1.12, 95%CI 1.02 to 1.23, P=0.02; RR=1.20, 95%CI 1.11 to 1.29, P < 0.000 01; RR=1.18, 95%CI 1.07 to 1.31, P=0.000 7), the 1-year, 2-year, and 3 year of progressions free survival (RR=1.18, 95%CI 1.08 to 1.28, P=0.000 2; RR=1.20, 95%CI 1.06 to 1.36, P=0.003; RR=1.48, 95%CI 1.25 to 1.74, P < 0.000 01), the complete remission rate (RR=1.67, 95%CI 1.26 to 2.23, P=0.000 4), and the overall response to chemotherapy (RR=1.18, 95%CI 1.11 to 1.27, P < 0.000 01). As for the side effect, the FP group was superior to the TFP group in the neutropenia (RR=1.42, 95%CI 1.24 to 1.63, P < 0.000 01), alopecia (RR=16.09, 95%CI 4.59 to 56.38, P < 0.000 1), and febrile neutropenia (RR=2.21, 95%CI 1.29 to 3.80, P < 0.004). ConclusionThe fluorouracil with cisplatin and fluorouracil for advanced head and neck squamous cell carcinoma might have better effects, but with higher side effects.
