Aim. Evaluation of long-term results of perioperative regional chemotherapy with gemcitabine and oxaliplatin in combined treatment of ductal adenocarcinoma of the pancreatic head. Material and methods. The first group consisted of 52 patients who received combined treatment: neoadjuvant chemoembolization (CE) with gemcitabine (400 mg / m2) and oxaliplatin (50 mg / m2) (GemOx), operative treatment, as well as up to 6 courses of chemoinfusion (CI) in the celiac trunk of gemcitabine (1000 mg / m2) and oxaliplatin (75 mg / m2) in the adjuvant regime. In the second group of 51 patients, perioperative regional chemotherapy (neoadjuvant CE and adjuvant CI) with gemcitabine (1000 mg / m 2) (Gem) was performed. 54 patients of the third group performed only operative intervention. Results. No complications associated with medical-diagnostic angiography and catheterization were observed. The median of life expectancy in the group of patients who received only operative treatment was 8.4 ±1.2 months, in the group of perioperative chemotherapy Gem-22.3 ± 1.5, in the group of patients who underwent perioperative regional chemotherapy GemOx-26 ± 1.1 months. Five-year survival rates in the groups were 0%, 10% and 13% and respectively Conclusions. A use of regional chemotherapy with gemcitabine and oxaliplatin can be regarded as a useful and effective step in combined treatment of pancreatic head adenocarcinoma.
Aim. To determine the effectiveness of regional chemotherapy (RChT) in the treatment of patients with unresectable colorectal metastases to the liver, resistant to systemic chemotherapy (SChT). Materials and methods. Between 2011 and 2017, we treated 60 patients with unresectable colorectal metastases to the liver, resistant to SChT from 2011 to 2017 y. All patients received previously 3-35 cycles of SCht which were ineffective in 54 and was discontinued in 6 patients because of grade III-IV toxicity. In all patients, antitumor drugs which were most effective in SChT were used for RChT,. In the absence of effect on any schemes of SChT, monotherapy with the Mitomycinum C was done. Hepatic arterial infusion (HAI) was carried out for hypovascular metastases using 4-6 gr 5-fluorouracil, 15-20 mg mitomycinum C, 150-200 mg oxaliplatinum, 160200 mg irinotecan. Transcatheter arterial chemoembolization (TACE) for hypervascular metastases was performed by selective infusion of suspension of Lipidol with chemotherapeutic drug: mitomycin C 10-20 mg or irinotecan 160-200 mg or doxorubicinum 50-80 mg and followed by arterial occlusion by gelfoam. Combination, TACE+HAI, was performed with difficult anatomical variants of hepatic artery. Results. We performed 222 cycles of RChT (from 2 to 15, average 6 per patient). There were no complication and lethality. Time to progression after the onset of RChT was 12.4 months in both groups. The median survival from the start of the first cycle SChT was 22 mo in the group with synchronous metastases of colorectal cancer to the liver and 23 mon for metachronic group. Conclusion. Our preliminary results showed prospect of using RChT in the treatment of patients with chemo-resistant colorectal metastases to the liver.
Aim. To evaluate the safety and efficacy of hepatic arterial infusion (HAI) in patients with Klatskin tumor. Materials and methods. Between 2010-2021, 14 of 119 patients with inoperable Klatskin tumor were treated with HAI of GEMICS. All patients had obstructive jaundice and received percutaneous transhepatic biliary drainage (PTBD). Chemotherapy was started when serum bilirubin level became normal (average on the 106th day from PTBD). In total, 19 (from 1 to 4 per patient) HAI cycles were performed. Results. PTBD complications such as cholangitis (n=2) and local peritonitis (n=1) developed in 3 patients (21%) and were successfully treated using minimally invasive techniques. Toxicity of chemotherapy were observed in 8 of 14 patients (57%): I-II degree hematological (43%) and gastrointestinal (50%); all were cured by medical therapy. The overall mean survival was 286 days (9.6 months), median survival 283 days (9.4 months). Conclusions. Our preliminary results showed that HAI in patients with Klatskin tumor is safe, but has limited effectiveness. The combination of arterial infusion with other methods such as radiotherapy, intra-ductal photodynamic therapy, radiofrequency ablation, target therapy, should be investigated.
During the period 2006 to 2017 years 86 patients with neuroendocrine pancreatic tumors were observed and treated. 25 (29,1%) patients underwent only chemotherapy due to generalized tumor process or severe concomitant somatic status. 61 (70,9%) patients with neuroendocrine pancreatic tumors underwent surgical treatment. In 34 patients tumors were localized in the body and tail, in 27 - in the head of the pancreas. Women predominated among patients (n = 41), the average age of the patients was 51 ± 3.1 years. Synchronous metastatic liver metastases were detected in 33 (54,1%) of 61 patients, with the size of the primary tumor from 10 to 73 mm. In 47 (77%) neuroendocrine pancreatic tumors were regarded as non-functioning. Radical surgery was performed in 24 patients of 61 (39,3%) with tumor sizes from 11 to 128 mm (average 56 ± 21 mm), cytoreductive surgery was performed in 37 (60.7%) patients. Patients with locally advanced neuroendocrine pancreatic tumors (n = 13) and neuroendocrine pancreatic tumors with synchronous liver metastases (n = 33) undergone combined treatment (n = 46). Combined treatment was performed by means of intra-arterial selective oil chemoembolization and chemoinfusion, supplemented with one or several local methods effects: cytoreductive surgery and radiofrequency ablation (n = 8). 6 (12.2%) of patients with high, moderately and low-grade tumors died after the operation in period from 7 to 63 months from progression of disease. 43 (87.8%) patients survived in period from 4 to 112 months, 32 patients still alive without signs of disease progression. Because of recurrence in five patients (11.9%) repeated operations were performed. One patient (2.4%) underwent conformal radiation therapy. Life expectancy after surgery in patients with low-grade neuroendocrine cancer of the pancreas ranged from 3 to 16 months, and the median survival was 8.3 ± 1.2 months.
