Cytoreductive Surgery Combined With Intraoperative Hyperthermic Intrathoracic Chemotherapy for Stage I Malignant Pleural Mesothelioma

Background:Malignant pleural mesothelioma (MPM) is a disease mostly confined to the thoracic cavity. Untreated, the median survival is <1 year. Cytoreductive surgery combined with intraoperative hyperthermic intrathoracic chemotherapy is used to kill residual tumor cells on the surface of the thoracic cavity while having limited systemic side effects.Methods:From August 1998 to August 2001, 22 patients with stage I MPM were included in this study. Two patients were irresectable at operation because of extrathoracic tumor growth. Twenty procedures were performed. After cytoreduction, a perfusion was performed with cisplatin and doxorubicin at 40°C to 41°C for 90 minutes. Adjuvant radiotherapy was given to surgical scars and drainage tracts.Results:There was no perioperative mortality, but significant morbidity was seen in 13 patients (65%), including bronchopleural fistula, diaphragm rupture, wound dehiscence, persistent air leakage, and chylous effusion. No hair loss or leucopenia was noticed. The median follow-up was 14 months. The median survival (Kaplan-Meier) was 11 months, with a 1-year survival of 42%. A favorable pharmacokinetic ratio was observed for both cisplatin and doxorubicin.Conclusions:Cytoreductive surgery combined with hyperthermic intrathoracic chemotherapy for stage I MPM is feasible. However, this treatment is accompanied by considerable morbidity. Survival data were less encouraging.     

Cytoreductive Surgery Combined With Hyperthermic Intraperitoneal Intraoperative Chemotherapy for Peritoneal Carcinomatosis Arising From Colon Adenocarcinoma

Background: Hyperthermic intraoperative intraperitoneal chemotherapy (HIIC) has been recently proposed to treat peritoneal carcinomatosis arising from colon adenocarcinoma, which is usually regarded as a lethal clinical entity. The purpose of this study was to evaluate the clinical outcome of this combined treatment.Methods: A retrospective study of 46 patients treated for peritoneal carcinomatosis from colon adenocarcinoma was performed. Thirty-four patients were treated with complete cytoreductive surgery immediately followed by intraoperative HIIC with mitomycin C and cisplatin. The clinical outcome of these 34 patients was analyzed; the median follow-up period was 14.5 months.Results: No postoperative deaths were reported. The postoperative morbidity rate was 35%. No severe locoregional or systemic toxicity was observed. The 2-year overall survival was 31%, and the median survival time and the median time to local disease progression were 18 and 13 months, respectively. Survival and local disease control in patients with well- and moderately differentiated colon adenocarcinoma were significantly better than in those with poorly differentiated tumors.Conclusions: Considering the dismal prognosis of this condition, HIIC seems to achieve encouraging results in a selected group of patients affected with resectable peritoneal carcinomatosis arising from colon adenocarcinoma. These findings support the conduction of formal phase III randomized trials.     

Limited Cardiotoxicity after Extensive Thoracic Surgery and Intraoperative Hyperthermic Intrathoracic Chemotherapy with Doxorubicin and Cisplatin

Background Recently, pleural mesothelioma has been treated by cytoreductive surgery and intraoperative hyperthermic intrathoracic chemotherapy with doxorubicin and cisplatin. The well-established cardiotoxicity of doxorubicin and distressing data from an animal study raised concern about its impact on cardiac function. In the present study, early cardiotoxicity of this treatment modality was prospectively analyzed. Patients and Methods In 13 pleural mesothelioma patients, cardiotoxicity was monitored by clinical examination, electrocardiography, Troponin levels, cardiac ultrasonography, and estimation of left ventricular ejection fraction (LVEF) by radionuclide ventriculography before and during the first 6 months after cytoreductive surgery and intraoperative hyperthermic intrathoracic chemotherapy with doxorubicin (25–54 mg/m²) and cisplatin (65–120 mg/m²). Results No clinical cardiac failure or treatment-related death was observed. In two patients transient atrial fibrillation was noted; one associated with pulmonary emboli. Early posttreatment Troponin release was not of predictive value. Ultrasonography did not reveal significant alterations. LVEF decreased significantly (mean 0.07 or 11%, P = .001) during the first 3 months and remained stable thereafter. In univariate analysis, the degree of LVEF reduction was statistically related to maximal intrathoracic doxorubicin concentration (P = .031) and total cisplatin dose (P = .029). Direct exposure of the heart to the drugs as a result of partial pericardectomy was not associated with greater LVEF decrease. On the contrary, partial pericardectomy seemed to be associated with a smaller LVEF decline than when the pericardium remained intact (P = .045). In this small series, no statistically significant correlation between other treatment or pharmacokinetic parameters and LVEF decline was found. Notably, higher doxorubicin plasma concentrations and exposure were not associated with increased LVEF reduction. Conclusions Early cardiotoxicity is limited after this treatment modality using substantial doses of doxorubicin and cisplatin. Hence, this study suggests that intrathoracic chemotherapy with doxorubicin and/or cisplatin may be used for primary and secondary pleural malignancies, even immediately after extensive thoracic surgery, without concern of severe early cardiotoxicity.     

Appendiceal Neoplasms With Peritoneal Dissemination: Outcomes After Cytoreductive Surgery and Intraperitoneal Hyperthermic Chemotherapy

Background Appendiceal neoplasms frequently present with peritoneal dissemination (PD) and have a clinical course marked by bowel obstruction and subsequent death. Few data have correlated outcome with appendiceal histology after cytoreductive surgery and intraperitoneal hyperthermic chemotherapy (IPHC). We have reviewed our experience with cytoreductive surgery and IPHC for PD from the appendix. Methods A total of 110 cases of PD from proven appendiceal neoplasms treated with IPHC were identified from a prospectively managed database. Tumor samples were classified on pathologic review as disseminated peritoneal adenomucinosis (n = 55), peritoneal mucinous carcinomatosis (PMCA) with intermediate features (n = 18), PMCA (n = 29), or high-grade nonmucinous lesions (n = 8). A retrospective review was performed with long-term survival as the primary outcome measure. Results A total of 116 IPHCs were performed on 110 patients for appendiceal PD between 1993 and 2004. The 1-, 3-, and 5-year survival rates for all cases were 79.9% ± 4.1%, 59.0% ± 5.7%, and 53.4% ± 6.5%, respectively. When stratified by histology, disseminated peritoneal adenomucinosis and intermediate tumors had better 3-year survival rates (77% ± 7% and 81% ± 10%) than PMCA and high-grade nonmucinous lesions (35% ± 10% and 15% ± 14%; P = .0032 for test of differences between groups). Age at presentation (P = .0134), performance status (P < .0001), time between diagnosis and IPHC (P = .0011), resection status (P = .0044), and length of hyperthermic chemoperfusion (P = .0193) were independently associated with survival. Conclusions The data show that long-term survival is anticipated in most patients who are treated with cytoreduction and IPHC for appendiceal PD. The findings presented herein underscore the important prognostic characteristics that predict outcome after IPHC in patients with PD. In all, this work establishes a framework for the consideration of IPHC in future trials for appendiceal PD.     

Esophageal Leiomyomatosis Combined With Intrathoracic Stomach and Gastric Volvulus

Case Report:

A 42-year-old female presented with longstanding symptoms suggestive of gastroesophageal reflux disease improved after proton pump inhibitor treatment. An upper endoscopy revealed an intrathoracic position of the stomach (type 4 hiatal hernia) with no mucosal abnormality. Barium swallow demonstrated gastric herniation with gastric volvulus without stenosis. A computed tomographic scan confirmed the intrathoracic location of the stomach associated with thickening and edema of the gastric wall due to gastric volvulus, but no evidence of malignancy. The patient was scheduled for laparoscopic gastric repositioning with anterior hemifundoplication. Due to the incidental intraoperative finding of a large distal esophageal tumor (frozen section: esophageal leiomyomatosis), the operation was converted to conventional distal esophagectomy and proximal gastrectomy with reconstruction using a Merendino procedure. Final histology revealed extensive circumferential leiomyomatosis of the distal esophagus with a diameter of 10 cm. Esophageal leiomyomatosis is an extremely rare pathological finding with <100 cases reported in the literature.

Conclusion:

Any surgeon performing laparoscopic fundoplication has to be ready to deal with such unexpected findings, ie, converting the procedure and doing reconstruction with minimal morbidity. The Merendino procedure is a well-established reconstructive surgical option in cases of tumor formation at the gastroesophageal region with fewer postoperative morbidities like reflux symptoms.

Survival Benefit of Hyperthermic Intraperitoneal Chemotherapy for Recurrent Ovarian Cancer: A Multi-institutional Case Control Study

Background

Hyperthermic intraperitoneal chemotherapy (HIPEC) and complete surgical removal of the tumor, in relapsing patients may provide a clinical benefit. There is no consensus considering the place of HIPEC for patients who had first ovarian cancer relapse. To assess for possible efficacy of HIPEC on overall survival (OS) rates in this situation, we performed a multi-institutional study.

Methods

The current study was a retrospective case control multi-institutional study comparing a group of patients treated with HIPEC to a group of patients treated without HIPEC. Inclusion criteria were first relapse of a serous ovarian carcinoma and >6 months after the end of initial treatment. Exclusion criteria were another pathological subtype of ovarian cancer, a relapse at <6 months after initial treatment, and a second relapse or more. We aimed to assess OS, morbidity, and mortality rates and prognostic factors.

Results

From June 1997–July 2011, 42 patients were included, 23 in the HIPEC group and 19 in the control group. Each patient from the two groups had a complete secondary surgery at the time of the first relapse. At 4 years OS was 75.6 % in the HIPEC group and 19.4 % in the control group (p = 0.013). In a multivariate analysis, HIPEC and interval-free before the end of initial treatment were both independent prognostic factors.

Conclusion

When compared to the control group, complete secondary surgery and HIPEC appear to afford a better OS rate than complete secondary surgery alone, in case of first ovarian cancer relapse. Further randomized trials are warranted to confirm these results.

Lung Transplant in a Patient With Multifocal Langerhans Cell Histiocytosis After Chemotherapy With Cladribine: A Case Report

Langerhans cell histiocytosis (LCH) is a rare inflammatory disorder of myeloid dendritic cells with mutations involving KRAS, BRAF and/or NRAS, and MAP2K1 genes.We describe the case of a 58-year-old female previous smoker with multifocal LCH involving the lungs, pituitary gland and mandibular bone. Initial treatment with 6 cycles of cladribine showed improvement in her extrapulmonary lesions, however, her lung disease progressed and after qualification and assessment tests she underwent uncomplicated double lung transplant surgery and was discharged home. We highlight that in select patients with well managed and controlled extrapulmonary LCH, such an invasive procedure as lung transplant is possible.     

High-Dose Chemotherapy With Autologous Stem Cell Transplantation in a Case of Refractory Peripheral T Cell Lymphoma With Tracheoesophageal Fistula: A Case Report

A 46-year-old woman with a sore throat was diagnosed with anaplastic lymphoma kinase-negative anaplastic large cell lymphoma that had spread from the piriform fossa to the cervical esophagus. Tracheoesophageal fistula developed after induction chemotherapy. Because conservative repair was not applicable, intensified chemotherapy, including autologous stem cell transplantation was performed with the fistula remaining open. Laryngopharyngectomy and cervical esophagectomy were performed 6 months after transplantation. The optimal strategy for refractory lymphoma with active tracheoesophageal fistula remains undetermined. To the best of our knowledge, this is the first report describing the successful treatment of a patient with tracheoesophageal fistula who received high-dose chemotherapy supported by autologous stem cell transplantation.     

Cytoreductive Surgery and Intraperitoneal Hyperthermic Chemotherapy With Mitomycin C for Peritoneal Carcinomatosis from Nonappendiceal Colorectal Carcinoma

Background: Cytoreductive surgery (CS) and intraperitoneal hyperthermic chemotherapy (IPHC) are efficacious in patients with disseminated mucinous tumors of the appendix. We reviewed our experience using this approach for nonappendiceal colorectal cancer (NACC).Methods: We performed a retrospective chart review of a prospective database for patients undergoing CS and IPHC with mitomycin C for peritoneal carcinomatosis from colorectal primary lesions between December 1991 and April 2002.Results: There were 77 patients, with a median age of 54 years. Peritoneal carcinomatosis was synchronous and metachronous in 27% and 73% patients, respectively. Seventy-five percent of patients (n = 58) had received chemotherapy prior to IPHC. Complete resection of all gross disease was accomplished in 37 patients (48%). The mean carcinoembryonic antigen level decreased from a preoperative value of 31.2 to a postoperative value of 6.9 (P < .0001). Overall survival (OS) at 1, 3, and 5 years was 56%, 25%, and 17%, respectively. With a median follow-up of 15 months, the median OS was 16 months. Perioperative morbidity and mortality were 30% and 12%, respectively. Hematologic toxicity occurred in 15 patients (19%). Cox regression analysis identified poor performance status (P = .018), bowel obstruction (P = .001), malignant ascites (P = .001), and incomplete resection of gross disease (P = .011) as independent predictors of decreased survival. Patients with complete resection of all gross disease had a 5-year OS of 34%, with a median OS of 28 months.Conclusions: CS and IPHC with mitomycin C can improve outcomes for select patients with peritoneal spread from NACC. One third of patients who undergo complete resection of gross disease have long-term survival.     

Childbearing After Hyperthermic Intraperitoneal Chemotherapy: Results From an International Survey

Background  

Cytoreductive surgery (CRS) and heated intraperitoneal chemotherapy (HIPEC) can improve survival in selected patients with primary or secondary peritoneal malignancies. With the opportunity for long-term survival, questions about the impact of those procedures in fertility in women of childbearing age can be raised.     

Case Report: First Reported Combined Heart-Liver Transplant in a Patient With a Congenital Solitary Kidney

We report a case of successful combined heart liver transplant in a patient with a congenital solitary kidney. The patient had normal renal function before combined heart-liver transplantation and developed acute kidney injury requiring slow continuous dialysis and subsequent intermittent dialysis for almost 8 weeks post transplantation. Her renal function recovered and she remains off dialysis now 7 months post transplantation. She only currently has mild chronic renal insufficiency. We believe this is the first reported case of successful heart liver transplant in a patient with a congenital solitary kidney.     

Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy in Asian Patients: 100 Consecutive Patients in a Single Institution

Background

Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) have been shown to improve survival in selected patients with peritoneal carcinomatosis. We review our institutional experience with the procedure and evaluate the overall survival (OS) and disease-free survival (DFS) rates in 100 consecutive patients.

Methods

Data were prospectively collected from 100 consecutive patients with peritoneal carcinomatosis treated by CRS and HIPEC at the National Cancer Centre Singapore between April 2001 and May 2012. Our primary end points were OS and DFS.

Results

Of the 100 patients, 84 were of Chinese ethnicity, 3 were Malay, 6 were Indian, and 7 were of other ethnicities. Primary tumors were ovarian cancer (n = 39), colorectal cancer (n = 28), primary peritoneal (n = 6), appendiceal cancer (n = 20), and mesothelioma (n = 7). Median follow-up duration was 21 months. At 5 years, the DFS was 26.3 % and OS was 50.9 %. Factors influencing OS and DFS were cytoreductive score, primary cancer, and disease-free interval of more than 12 months on univariate analysis. The only factors that remained significant for prognosis after multivariate analysis were primary cancer and cytoreductive score. Thirty-day morbidity was 56 %, and there were no 30-day mortalities.

Conclusions

CRS and HIPEC can be safely carried out in Asian patients with peritoneal carcinomatosis from ovarian, colorectal, appendiceal, mesothelioma, and primary peritoneal origins. Overall, the ovarian, appendiceal, mesothelioma, and primary peritoneal cancer patients tended to do better than the colorectal patients, but careful patient selection ensuring that optimal cytoreduction can be achieved is essential for the success of this procedure.     

术中腹腔内温热化疗在胃癌外科综合治疗中的临床意义

过去30年来,针对胃癌的外科综合治疗,人们将主要精力投入于研究癌肿淋巴结的转移规律,并据此普遍地采用了扩大的淋巴结清扫术,使胃癌根治性手术后淋巴结复发的状况明显改观,患者术后生存率有了较大改善。然而,单纯外科手术并未能有效地防治术后腹膜的转移复发,并以此正逐渐成为胃癌术后的主要复发类型。Yonemura［1,2］等报道,胃肠道癌肿术后复发患者中,50%以上存在腹膜转移或复发,且已成为导致患者死亡最主要的因素之一。因而如何积极地采取有效措施防治术后腹膜转移复发已成为胃癌临床研究中亟待解决的问题。全身性化疗治疗腹…     

Closed Abdomen Hyperthermic Intraperitoneal Chemotherapy with Irinotecan and Mitomycin C: a Phase I Study

Purpose  

Cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy (HIPEC) is now a recognized treatment for peritoneal carcinomatosis (PC). The objective of this phase I study is to determine the maximum tolerated dose of irinotecan (CPT-11) when used with mitomycin C (MMC) for closed abdomen HIPEC.     

Combined Intestine and Kidney Transplantation in a Patient With Encapsulating Peritoneal Sclerosis: Case Report

Encapsulating peritoneal sclerosis (EPS) is a rare but devastating complication of peritoneal dialysis characterized by fibrosis and calcification of the intestine that, in severe cases, can progress to intestinal failure and total parenteral nutrition dependency. Medical and surgical interventions carry a poor prognosis in these patients. We describe a case of a 36‐year‐old female with end‐stage kidney disease and severe EPS not amenable to surgical intervention who underwent a combined intestinal and kidney transplantation. At 3 years posttransplantation, the patient has normal intestinal and kidney function. This represents, to our knowledge, the first report of severe EPS and end‐stage kidney disease treated with a combined transplant.
