Treading the beaten path with old and new obstacles: a report from the Indian HIPEC registry.

BACKGROUND: The Indian HIPEC registry is a self-funded registry instituted by a group of Indian surgeons for patients with peritoneal metastases (PM) undergoing surgical treatment. This work was performed to • Evaluate outcomes of cytoreductive surgery ± HIPEC in patients enrolled in the registry. • Identify operational problems. METHODS: A retrospective analysis of patients enrolled in the registry from March 2016 to September 2017 was performed. An online survey was performed to study the surgeons' attitudes and existing practices pertaining to the registry and identify operational problems. RESULTS: During the study period, 332 patients were enrolled in 8 participating centres. The common indication was ovarian cancer for three centres and pseudomyxoma peritonei for three others. The median PCI ranged from 3 to 23. A CC-0/1 resection was obtained in 94.7%. There was no significant difference in the morbidity (p = .25) and mortality (p = .19) rates between different centres. There was a high rate of failure-to-rescue (19.3%) patients with complications and the survival in patients with colorectal PM was inferior. A lack of dedicated personnel for data collection and entry was the main reason for only 10/43 surgeons contributing data. The other problem was the lack of complete electronic medical record systems at all centres. CONCLUSIONS: These results validate existing practices and identify country-specific problems that need to be addressed. Despite operational problems, the registry is an invaluable tool for audit and research. It shows the feasibility of fruitful collaboration between surgeons in the absence of any regulatory body or funding for the project.

Hyperthermic Intrathoracic Chemotherapy (HITHOC) for Pleural Malignancies-Experience from Indian Centers.

Hyperthermic intrathoracic chemotherapy (HITHOC) has been used in addition to radical surgery for primary and secondary pleural malignancies to improve local control, prolong survival, and improve the quality of life. This study was performed to study the indications, methodology, perioperative outcomes, and survival in patients undergoing HITHOC at Indian centers. A retrospective analysis of prospectively collected demographic and clinical data, perioperative and survival data of patients undergoing surgery with or without HITHOC was performed. From January 2011 to May 2018, seven patients underwent pleurectomy/decortication (P/D) or extrapleural pneumonectomy (EPP) with HITHOC and four had P/D or EPP alone at three Indian centers. P/D was performed in two and EPP in nine patients. The primary tumor was pleural mesothelioma in eight, metastases from thymoma in one, germ cell tumor in one, and solitary fibrous tumor of the pleura in one. HITHOC was performed using cisplatin. Grade 3-4 complications were seen in one patient in the HITHOC group and none in the non-HITHOC group, and one patient in the non-HITHOC group died of complications. At a median follow-up of 9 months, five patients of the HITHOC group were alive, four without recurrence, and one with recurrence. One patient in the non-HITHOC group was alive and disease-free at 24 months, and two died of progression at 18 and 36 months. HITHOC can be performed without increasing the morbidity of P/D or EPP. Most of these patients require multimodality treatment and are best managed by multidisciplinary teams.

Revision surgery for breast cancer: single-institution experience.

At Tata Memorial Hospital, as a dedicated breast service at a tertiary cancer center in India, incompletely performed breast surgeries are encountered very frequently; however, there is a lack of published data on incompletely performed breast surgeries, revision surgeries, and their outcomes. Between March 2000 and November 2003, the authors audited 850 breast cancer patients who presented at their institute who had undergone surgery outside the institution. On the basis of study criteria, these patients were evaluated for completeness of surgery. Patients in whom the surgical intervention was considered incomplete were evaluated for a completion revision surgery. Of 850 patients, 424 (50%) had undergone surgical intervention with therapeutic intent. Of these 424 patients, 191 (45%) had received incomplete surgical intervention. Completion revision surgery was performed for 153 patients. Complete data were available for 148 patients, of which 123 patients had residual lymph nodes in the axilla. The median number of lymph nodes dissected was 8, and 64 patients had metastatic lymph node(s) left behind. A high proportion of patients with breast cancer who presented at the institute had undergone incomplete surgery outside in nonspecialty centers. Almost half of those patients who underwent incomplete surgery had surgically excisable disease left behind. The possible detrimental impact of inadequate surgical intervention may be very large in India and in other low-resource settings.

Influence of surgical technique on axillary seroma formation: a randomized study.

The aim of this study was to evaluate the influence of surgical technique in the form of electrocautery and suction drains on seroma formation following surgery for breast cancer. A prospective randomized study was carried out. One hundred and sixty patients with breast cancer who underwent surgery were allocated to four arms using a 2 x 2 factorial design. This method enabled us to evaluate the independent effect of two different causative factors on the incidence of postoperative seroma formation using a single dataset with limited numbers. The main outcome measure was postoperative seroma formation defined as a postoperative axillary collection requiring more than one aspiration after removal of the drain. The incidence of seroma in our institution is 90%. Incidence of postoperative seroma was 88.3% if electrocautery was used, which reduced to 82.2% if surgery was carried out using scissors for dissection and ligatures for haemostasis (P = 0.358). There was no influence on the incidence of seroma formation whether suction drain (84.6%) or corrugated drains (86.1%) were used (P = 0.822). The use of electrocautery in axillary dissection does not adversely affect postoperative seroma formation after surgery for breast cancer. The use of different drainage techniques has no bearing on the postoperative seroma formation. The surgical technique has no influence on the rate of seroma formation after surgery for breast cancer.

Leiomyoma of esophagus.

Leiomyomas are rare benign esophageal neoplasms with an indolent clinical course. Symptoms mimic that of esophageal cancer. Esophagoscopy and endoscopic ultrasonography are the main diagnostic methods. Symptomatic and large leiomyomas should be treated surgically while small, asymptomatic lesions may be managed by regular follow up and repeated endoscopies.

Setting up of the Indian HIPEC Registry: A Registry for Indian Patients with Peritoneal Surface Malignancies.

There are various registries for patients with peritoneal metastases (PM) that aid pooling of data and generate evidence that dictates current clinical practice. This manuscript describes the setting up of the Indian HIPEC registry that was set up with a similar goal by a group of Indian surgeons. This is a registry for patients with PM treated with CRS and HIPEC in India. It also acts as a database for storing treatment-related information. Patients with PM from colorectal ovarian, gastric, appendiceal tumors, and other rare peritoneal tumors/metastases from rare tumors are enrolled in the registry. A coordinator updates the disease status of patients on a yearly basis. A private organization maintains the database. A non-disclosure agreement is signed between the company and each surgeon contributing to the registry to maintain confidentiality. For enrolling patients, securing institutional permission depends on the requirement of each institute; patient consent is mandatory. Data entry can be prospective or retrospective. To propose and conduct a study, the approval of a scientific committee linked to the registry is required. The Indian HIPEC registry is a practical database for Indian surgeons. There is no regulatory body that mandates collection and publication of scientific data in India. The onus is on each surgeon to capture valuable information pertaining to these common and rare diseases that could contribute to the existing scientific knowledge and guide the treatment of these patients in the future. The next challenge will be to enter data into the registry.
