Is intra-arterial hepatic chemotherapy painful?

BACKGROUND: Liver metastases are mainly supplied by the hepatic artery, allowing the administration of intra-arterial hepatic chemotherapy (IAHC) while preserving normal parenchyma. The progression-free survival and response rate are prolonged by IAHC which can improve the rate of secondary resectability. Severe abdominal pain requiring high-dose opioids can appear during HIAC administration. This pain is related to extrahepatic infusion and gastroduodenal ulceration. However, intense abdominal pain was observed under oxaliplatin IAHC specifically without any extrahepatic infusion. METHOD: We retrospectively reviewed the charts of 68 patients who received IAHC in our center between 2011 and 2015. Patient's demographics and disease characteristics were collected. Other variables such as the type, duration, and dosage of the chemotherapy administered, as well as the usage of painkillers before, during, or after intra-arterial administration, were also registered. RESULTS: The mean age of the patients was 59 years. 61.7% were male (n = 42). The mean dose of oxaliplatin administered was 162 mg per cure over 6.7-h course. Fifty percent were diagnosed with a left colon cancer, and 85.2% had synchronous liver metastasis. While 47% of patients received IAHC as a third-line therapy, the main chemotherapeutic drug was oxaliplatin (85.2% of cases; n = 58), then OPTILIV protocol (5FU, irinotecan, oxaliplatin) (13.3%; n = 9), and mitomycin C (1.5%; n = 1). A dose reduction of 23.6% had been noted in 58.8% (n = 40) cases due to adverse effects. Among patients who received opioids during IAHC (n = 40), 20% required opioids in intercure. Before, during, and after IAHC administration, patients complained of abdominal pain in 8.8%, 58.8%, and 19.1%, and opioids were used in 10.2%, 57.3%, and 19.1%, respectively. The main onset of pain occurs during the third cycle of chemotherapy. Among our patients, 11.7% and 22% had ulcer and extrahepatic perfusion, respectively, while 7.3% of them were asymptomatic. The mean occurrence of these signs was during the fourth cycle of IAHC. 33.8% and 52.9% of patients had abdominal pain while an extended and short infusion time, respectively. CONCLUSION: Lengthening of the infusion time did not prevent the occurrence of abdominal pain significantly but was nonetheless decreased compared with patients undergoing short infusion durations. Pain was more common in patients who did not have a dose reduction and who presented with ulcer and extrahepatic perfusion. Abdominal pain occurred on average one cycle before ulcer or extrahepatic perfusion diagnosis. In current practice, pain should be an alarming indicator in patients receiving IAHC, as it may be associated with ulcer or extrahepatic perfusion and thus requiring opioids.

[Treatment of metastatic progression following the synchronous occurrence of cutaneous and ocular primary melanomas]. / Metasztatikus progresszió kezelése primer cutan és ocularis melanoma szinkrón elofordulását követoen.

The incidence rates of cutaneous melanoma in non-Hispanic whites show an increasing tendency with age. While uveal melanoma in general is a rare disease, representing only 4% of all melanomas with an incidence rate of 0.6 per 100 000, it is still the most frequent malignancy of the eye. Synchronous occurrence of ocular and cutaneous melanoma is an exceptional rarity, due to the distinct genetic background of the diseases. We report the case of a 80-year-old man who underwent total excision of a cutaneous melanoma in 2008. In 2013, he was diagnosed with uveal melanoma as part of a routine work-up for reduced vision. The uveal melanoma was treated by brachytherapy. In 2015, liver metastases were suspected by routine ultrasonography. Core biopsy was carried out, and the histology confirmed melanoma metastases. The molecular analysis of the cutaneous lesion showed gain of function mutation of the BRAF V600 K gene, while we found a wild-type BRAF gene in the metastatic lesion. Based on the recommendation of the oncoteam, hepatic intra-arterial Epirubicin-Platidiam therapy was introduced. He received 11 doses of intra-arterial chemotherapy (IAC), in 21 cycles. IAC was well tolerated without any catheter-related complications or toxicities. Partial regression of the hepatic metastases were documented in February 2016. After completing the eleventh cycle of intrahepatic chemotherapy, the disease remained in complete remission for over a year. The parallel occurrence of cutaneous and ocular melanoma is rare, however, the metastatic progression in such cases make the selection of optimal medical therapy challenging. The distinct genetic background of two melanoma types may help the identification of the source of the metastatic lesions, in order to guide the treatment decisions.

Intra-arterial hepatic bevacizumab and systemic chemotherapy in hepatic metastasis of colorectal cancer: A phase II multicentric trial in second-line treatment.

INTRODUCTION: Intra-arterial hepatic (IAH) treatment has shown promising results in the management of patients with unresectable colorectal liver metastases (CRLM) the prognosis of which is poor. Bevacizumab adjunction to standard chemotherapy has been shown to improve survival of this patient population. This prospective study was conducted to assess the efficacy and safety of IAH bevacizumab combined to systemic chemotherapy after first-line treatment failure in patients with CRLM. METHODS: Included patients had dominant or isolated unresectable CRLM progressing after standard first-line treatment for metastases of colorectal cancer. Three patients had less than 30% liver invasion, three patients between 30 and 50%, two more than 50% and data was missing in two patients. An intra-hepatic catheter was implanted surgically or percutaneously. Bevacizumab 7.5 mg/kg was administered once every 3 weeks in combination with capecitabine 2000 mg/m² per day for 2 weeks and oxaliplatin 130 mg/m² or irinotecan 200 mg/m² once every 3 weeks. The primary end-point was the objective response rate. RESULTS: Between June 2013 and February 2015, 10 patients were included. The trial was prematurely closed because of the lack of financial support and poor accrual. The patients had a median of 6 [1-9] cycles of treatment. Partial response was achieved in 2 patients (20%) and a R0 liver metastases resection in one another. All patients died of disease progression. The median overall and progression-free survival rates were respectively 14.0 (95% IC [4.8 - 25.8] and 5.4 months (95% IC [1.6 - 6.2]). Four patients had severe side effects but no toxic death occurred. CONCLUSION: IAH bevacizumab combined to systemic chemotherapy is feasible and safe in patients with unresectable isolated or dominant CRLM progressing after a first-line systemic treatment. Based on the low number of patients included in our study, our results suggest that this treatment does not increase dramatically the response rate versus an adapted systemic treatment. However, considering the safety data provided in this study, arterial infusion of bevacizumab in adjunction to chemotherapeutic agents could be evaluated in the future.

Intra-arterial hepatic chemotherapy for unresectable colorectal liver metastases: a review of medical devices complications in 3172 patients.

BACKGROUND: Hepatic artery infusion (HAI) is indicated to treat unresectable colorectal hepatic metastases, with recent applications as a neoadjuvant or adjuvant treatment. Traditionally performed with the infusion of fluoropyrimidine-based chemotherapy, it has been now tested with oxaliplatin or irinotecan and associated with systemic chemotherapy. METHODS: To evaluate the impact of medical devices complications we carried out a search of the published studies on HAI in unresectable colorectal liver metastases. Complications were pooled according to the applied medical system: 1) surgical catheter, 2) radiological catheter, and 3) fully implantable pump. The surgical catheter is inserted into the hepatic artery from the gastro-duodenal artery. The radiological catheter is inserted into the hepatic artery through a percutaneous transfemoral or transaxillar access. The fully implantable pump is a totally internal medical device connected to the arterial hepatic catheter during laparotomy. RESULTS: The selection criteria were met in 47/319 studies. The complications of surgical and radiological medical devices connected to a port were found in 16 and 14 studies respectively. Meanwhile, complications with a fully implantable pump were reported in 17 studies. The total number of complications reported in studies evaluating patients with surgical or radiological catheter were 322 (322/948, 34%) and 261 (261/722, 36.1%) respectively. In studies evaluating patients with a fully implantable pump, the total number of complications was 237 (237/1502, 15.8%). In 18/319 studies the number of cycles was reported. The median number of cycles with surgically and radiologically implanted catheters was 8 and 6 respectively. The fully implantable pump allows a median number of 12 cycles. CONCLUSIONS: The fully implantable pump, maintaining a continuous infusion through the system, allows the lowest risk for thrombosis and infection and the best median number of cycles of loco-regional chemotherapy in HAI.
