Isolated thoracic perfusion in lung metastases from breast cancer: a retrospective observational study

Therapeutic Effect of Regional Chemotherapy in Diffuse Metastatic Cholangiocarcinoma

Simple Summary

Cholangiocarcinoma are mostly diagnosed at a late stage and early recurrence is also very common with 5-year survival rates of <5% in unresectable, and 33% in resectable disease. Systemic therapy options are limited with unsatisfactory outcome. The aim of our study was to assess the efficacy of regional chemotherapy in diffuse metastatic cholangiocarcinoma. In 36 diffuse metastatic cholangiocarcinoma patients 189 cycles of regional chemotherapy using arterial infusion and perfusion techniques have been applied. Regional chemotherapy provided an excellent outcome with a median therapy specific survival of 12 months. Regional chemotherapy is effective and superior to current available and proposed therapy options in diffuse metastatic cholangiocarcinoma.

Abstract

Background: Current therapeutic options in diffuse metastatic cholangiocarcinoma (CCC) are limited with unsatisfactory results. We evaluated the efficacy of regional chemotherapy (RegCTx) using arterial infusion (AI), hypoxic stop-flow abdominal perfusion (HAP), upper abdominal perfusion (UAP) and isolated-thoracic perfusion (ITP) in 36 patients with metastatic perihilar and intrahepatic CCC. Methods: Ten patients had previously undergone a liver resection and in 14 patients the previous systemic chemotherapy (sCTx) approach had failed. A total of 189 RegCTx cycles (90 AI, 74 UAP, 13 HAP and 12 ITP) were applied using cisplatin alone or with Adriamycin and Mitomycin C. A minimum of three cycles were applied in 75% of the study population. The response was evaluated using RECIST criteria with MediasStat 28.5.14. Mortality, morbidity and survival analysis were performed using a prospective follow-up database and SPSS–28.0. Results: No procedure related mortality occurred. The overall morbidity was 56% and dominated by lymph fistulas at the inguinal access site. No grade III or IV haematological complication occurred. The overall response rate was 38% partial response, 41% stable and 21% progressive disease. Median overall survival was 23 months (95%CI 16.3–29.7). The RegCTx specific survival was 12 months (95%CI 6.5–17.5) in completely therapy naive patients but also in patients who had failed a sCTx attempt previously. Conclusion: RegCTx is feasible, safe and superior to the current proposed therapeutic options in metastatic CCC. The role of RegCTx should be determined in a larger cohort of diffuse metastatic CCC patients but also at early stages especially in initially not resectable but potentially resectable patients.

Regional Chemotherapy Is a Valuable Second-Line Approach in Metastatic Esophageal Cancer after Failure to First-Line Palliative Treatment

Background: Therapeutic options in metastatic esophageal cancer (EC) are limited with unsatisfactory results. We evaluated the efficacy of regional chemotherapy (RegCTx) approach in diffuse metastatic EC using arterial infusion (AI), upper abdominal perfusion (UAP) and isolated-thoracic perfusion (ITP) in 14 patients (N = 8 adenocarcinoma (AC) and N = 6 squamous cell carcinoma (SQCC)) after failure to first-line palliative treatment. Methods: All patients had previously failed first-line palliative treatment attempt with systemic chemotherapy (sCTx). In total 51 RegCTx cycles (12 AI, 3 UAP and 36 ITP) were applied using cisplatin, Adriamycin and Mitomycin C. The outcome was evaluated using RECIST criteria with MediasStat 28.5.14 and SPSS–28.0. Results: No grade III or IV hematological complications occurred. The overall response rate was 41% partial response, 27% stable and 32% progressive disease. Median overall survival (OS) was 38 months (95%CI 10.1–65.9). The OS was better in SQCC with 51 months The RegCTx specific survival was 13 months (95%CI 2.9–23.1) in the entire cohort and 25 months in SQCC patients. Conclusion: RegCTx is a valuable safe approach and superior to the current proposed therapeutic options in metastatic EC after failure to first-line therapy.

Tumor response and the quality of life after isolated hypoxic pelvic perfusion for advanced G3 cervical cancer: A case series

•

Standard treatment of cervical cancer is associated with considerable toxicity and permanent adverse events.

•

Isolated hypoxic pelvic perfusion overcomes chemoresistance and generates effective and onlasting tumor response.

•

Complete and durable clinical and radiological remissions are achieved with no identifiable signs of systemic toxicity.

•

Quality of life is maintained.

Introduction

We present a case series of three patients with advanced cervical cancer who either refused the standard of care systemic or chemoradiation treatment or did not benefit from it.

Methods

We treated patients with isolated hypoxic pelvic perfusion (HPP).

Results

Two patients achieved complete clinicopathologic response and one patient required surgical excision of the necrotic residual mass containing no viable cancer cells. There were no long-term systemic or local side effects. All patients are cancer free for up to 15 years after conclusion of treatment.

Conclusion

HPP is an effective option for treatment of advanced cervical cancer that generates rapid and onlasting remissions at low side effects. Gynecologic oncologists shall be aware of HPP to facilitate wider adaption of our technique.

Approaching 10 years disease-free survival after isolated thoracic perfusion for advanced stage IV tonsil carcinoma: A case report

INTRODUCTION

This is a report about the first case of an advanced stage IV tonsil carcinoma treated with isolated thoracic perfusion and chemofiltration.

PRESENTATION OF CASE

The tumor extended beyond the midline with bilateral lymphnode metastases. Playing on wind instruments was impossible. As a professional Jazz saxophonist he refused mutilating surgery and chemoradiotherapy. After one isolated thoracic perfusion there was substantial tumor shrinkage. After three additional cycles of carotid artery infusion with chemofiltration a complete remission has been noted without systemic or local toxicity since 9 ½ years.

DISCUSSION

Knowing the often considerable long-term damage after surgery and chemoradiotherapy of head and neck tumors, some patient reject conventional therapy. Because of the steep dose response curve in cancer chemotherapy, an increased drug exposure in terms of intra-arterial short-term infusions or isolated perfusion can induce rapid remission induction without significantly affecting the quality of life. Further studies comparing regional chemotherapies with conventional chemoradiotherapy are warranted.

CONCLUSION

Intra-arterially applied short-term chemotherapy may generate rapid and onlasting remissions at low side-effects.
