Analysis on chronic pain management: Focus on the Italian network.

The Italian Law 38/2010, 'Dispositions to guarantee access to Palliative Care and Pain Management' orders that the health care systems of Italian regions create dedicated structures for palliative care and pain therapies, according to a specific organizational model called 'Hub-Spoke', to ensure the diagnostic-therapeutic continuity of patients affected by chronic pain (CP). The aim of our study was to investigate the Italian pain therapy network, 8 years following the approval of the Law. We sent a questionnaire to the national health representatives operating in CP management. The main result emerging from the analysis concerns the management of mini-invasive procedures, showing that 93.2% of the responding facilities carry out invasive procedures, 6.8% do not perform them and that 100% of the facilities belonging to 12 regions provided these procedures, while in eight regions more than 80%. Finally, only 38.5% of facilities declared to have a shared protocol with the relevant territorial facilities in order to guarantee the process of care and assistance of patients affected by CP. In conclusion, our study demonstrated the efficacy of the organizational model in most of the responding facilities, although the territorial management of patients after their hospital discharge should be strengthened.

High dosage of a fixed combination oxycodone/naloxone prolonged release: efficacy and tolerability in patients with chronic cancer pain.

PURPOSE: Opioids are associated with side effects in the treatment of moderate-to-severe chronic cancer pain. Oral combination of opioid agonist-antagonist oxycodone-naloxone (OXN-PR) attenuates gastrointestinal side effects; however, evidence on high-dose OXN-PR treatment is scant. This study evaluates the efficacy and tolerability of high-dose OXN-PR in chronic cancer pain. PATIENTS AND METHODS: This was a multicenter, prospective 60-day observation on consecutive cancer patients with uncontrolled moderate-severe chronic pain or intolerant to other analgesics, who were switched at entry visit (T0) to OXN-PR ≥80 mg daily. Patients were reassessed 14, 30, 45, and 60 days later (T60). Primary endpoint of the study was analgesic response rate (decrease ≥30% of pain intensity from baseline, measured on a 0-10 numerical rating scale, NRS) after 30 days on OXN-PR. Additional endpoints assessed at every visit were the impact of pain on quality of life (QoL), breakthrough cancer pain (BTCP) episodes, opioid dosage escalation index, bowel dysfunction, safety, and other side effects. RESULTS: One hundred nineteen patients were included (age 64 ± 12, metastatic disease in 91.6%); 101 of them (84.9%) completed the 60-day observation. At T0, the majority had severe pain (NRS ≥7 in 79.8%; neuropathic features in 83.2%). Response rate at 30-day visit was 79.8% (n = 95). OXN-PR resulted in a significant reduction in pain over time (T0: 7.4 ± 1.3; T60: 3.3 ± 1.8; p < 0.001), and the number of daily (BTCP) declined (3.9 ± 2.2 vs. 2.0 ± 0.6, p < 0.001). Daily dosage of OXN-PR slightly increased (T0: 81.3 ± 6.0; T60: 93.6 ± 34.0; p < 0.001). The impact of pain on QoL abated (p < 0.0001), and bowel function improved overtime (p < 0.001). After the switch to OXN-PR, the number of patients complaining for side effects decreased overall (p < 0.0001); laxatives and antiemetic use also declined significantly. CONCLUSIONS: OXN-PR was highly effective and well tolerated even at high doses in cancer patients with chronic pain. The agonist-antagonist combination rapidly alleviated pain and its impact on life style, reducing the number of BTCP and improving opioid side effects.

Targeted therapy in renal carcinoma: a case of long-term effect with complete control of toxicity.

Although advances in imaging techniques have allowed earlier diagnosis of renal cell carcinoma (RCC) in recent decades, one-third of patients who have undergone radical resection of organ-confined disease will eventually develop metastases. The treatment of metastatic RCC was revolutionized by the advent of targeted therapy with tyrosine kinase inhibitors. We have followed seven patients with metastatic RCC who were treated with first-line pazopanib at our center. The case of one of these patients is described here in detail. The patient was first diagnosed with RCC in 1999 and metastases were detected in 2006 and 2012. Treatment with pazopanib at the standard dose of 800 mg/day for 29 months led to a partial response that persisted over time. Side effects (hypertension and painful mucositis) were successfully managed with supportive care at our oral therapy clinic. Early management of adverse events using a multidisciplinary approach is paramount to the favorable outcome of treatment with pazopanib and other targeted agents.

Advanced adult esthesioneuroblastoma successfully treated with cisplatin and etoposide alternated with doxorubicin, ifosfamide and vincristine.

The esthesioneuroblastoma is a rare neuroendocrine tumor that derives from the olfactory cells. In the last 20 years, around 1,000 cases have been described, with an overall survival rate of 60-70% at 5 years. The most common symptoms are nasal bleeding, nasal clogging and, in locally advanced cases, signs/symptoms of intracranic hypertension such as papilla edema, cefalea, and vomiting. The standard treatments are surgery and radiotherapy. Chemotherapy can be used in an adjuvant/neoadjuvant setting and in the metastatic phase, even if its role is still not established with certainty. Here, the case is reported of a young man (38 years old) with a locally advanced esthesioneuroblastoma. Two months before coming to our clinic, he had been treated elsewhere with debulking surgery through bilateral frontal craniotomy. After surgery, MRI showed residual disease in the nasal cavities and in the medial wall of the orbits responsible for blindness and bilateral exophthalmos within a month: a very short time. Octreoscan and whole body CT scan confirmed a locally advanced disease, in the absence of metastases. Chemotherapy was begun with cisplatin and etoposide alternated with doxorubicin, ifosfamide and vincristine with granulocyte colony-stimulating factor (G-CSF) support after every cycle. Soon after the first cycle, an important reduction of pain and decrease of the exophthalmos and vertigos was observed. No improvement in blindness was seen. The patient is still stable after 24 months of follow up.

Preferences of patients with advanced colorectal cancer for treatment with oral or intravenous chemotherapy.

BACKGROUND: In recent years, patient-reported outcomes such as health-related quality of life have become important areas of clinician focus in general cancer management. Patients' preferences for, and/or satisfaction with, oral versus intravenous (IV) chemotherapy schedules may have a major impact on such outcomes. OBJECTIVE: To evaluate preferences for oral or IV chemotherapy in patients with advanced colorectal cancer. METHODS: A multicenter, randomized, crossover trial was conducted in 12 hospitals in Southern Italy, in which 22 patients with advanced colorectal cancer received one cycle of oral capecitabine ± irinotecan or oxaliplatin, followed by one cycle of an IV de Gramont or similar regimen (arm A), or the same regimens in reverse order (arm B). Patients were aged 50-70 years and 21% had a higher level of education (graduate or similar). Patients received oral capecitabine 3500 mg/m/day for 7 days (± irinotecan 180 mg/m or oxaliplatin 85 mg/m on day 1 only), followed by an IV de Gramont regimen ± irinotecan (FOLFIRI) or oxaliplatin (FOLFOX); or the two schedules administered in reverse order.The main outcome measure was patients' preferences for oral versus IV chemotherapy, as determined by a pre- and post-treatment therapy preference questionnaire (TPQ). RESULTS: Before treatment, 75% of patients preferred oral therapy. Characteristics that patients considered to be important were that treatment should not interfere with daily activities (100% of patients) and should not cause fatigue (95%), diarrhea (76%), or painful mouth ulcers (76%); other factors considered important were the risk of infection and nausea (90%), and that treatment could be administered at home (65%). After receiving both chemotherapy schedules, only 45% of patients preferred oral therapy, while 55% preferred IV therapy. Among the latter, the most important characteristics influencing treatment choice were less nausea (66%), fewer mood effects (65%), the safety of hospital IV treatment (62%), less interference with family relationships (55%), less vomiting (55%), less interference with daily activities (50%), and less diarrhea (50%). Although the order in which patients received therapy did not influence treatment preference, significantly fewer patients with a lower rather than higher educational level preferred oral therapy (47% vs 80%; chi-square test = 9.9; p = 0.002). CONCLUSION: These results suggest that there may be a correlation between educational level and the preference of patients with advanced colorectal cancer for oral or IV chemotherapy.
