    Simple Summary Catastrophism was not associated with the levels of pain intensity, PSG, PSGR, and PGI for pain, except the rumination subscale that was independently associated with pain intensity at T0. A comprehensive palliative care management provided the relevant changes in symptom burden and annulled the pain expression associated with rumination.Abstract Background: Pain catastrophizing is a group of negative irrational cognitions in the context of anticipated or actual pain. The aim of this study was to decipher the possible role of catastrophism on pain expression and outcomes after a comprehensive palliative care treatment. Methods: A consecutive sample of patients with uncontrolled pain was assessed. Demographic characteristics, symptom intensity included in the Edmonton symptom assessment system (ESAS), and opioid drugs used were recorded at admission (T0). The Pain Catastrophizing Scale (PCS) was measured for patients. Patients were also asked about their personalized symptom goal (PSG) for each symptom of ESAS. One week after a comprehensive palliative care treatment (T7), ESAS and opioid doses used were recorded again, and the number of patients who achieved their PSG (PSGR) were calculated. At the same interval (T7), Minimal Clinically Important Difference (MCID) was calculated using patient global impression (PGI). Results: Ninety-five patients were eligible. A significant decrease in symptom intensity was reported for all ESAS items. PGI was positive for all symptoms, with higher values for pain, poor well-being, and poor sleep. Only the rumination subscale of catastrophism was significantly associated with pain at T0 (B = 0.540; p = 0.034). Conclusions: Catastrophism was not associated with the levels of pain intensity, PSG, PSGR, and PGI for pain, except the rumination subscale that was associated with pain intensity at T0. A comprehensive palliative care management provided the relevant changes in symptom burden, undoing the pain expression associated with rumination

    Aim The aim of this study was to assess the efficacy and adverse effects of methadone when used as first-line therapy in patients that are either receiving low doses of opioids or none. Methods Patients with advanced cancer were prospectively assessed. Opioid-naive patients (L-group) were started with methadone at 6 mg/day. Patients receiving weak or other opioids in doses of <60 mg/day of OME (H-group) were started with methadone at 9 mg/day. Methadone doses were changed according to the clinical needs to obtain the most favorable balance between analgesia and adverse effects. Edmonton Symptom Asssement Score (ESAS), Memorial Delirium Assessment Score (MDAS), doses of methadone, and the use of adjuvant drugs were recorded before starting the study treatment (T0), 1 week after (T7), 2 weeks after (T14), 1 month after (T30), and 2 months after (T60). Methadone escalation index percent (MEI%) and in mg (MEImg) were calculated at T30 and T60. Results Eighty-two patients were assessed. In both groups H and L, there were significant changes in pain and symptom intensity at the different times during the study. Adverse effects as causes of drop-out were minimal. Mean MEImg was 0.09 (SD 0.28) and 0.02 (SD 0.07) at T30 and T60, respectively. MEI% was 1.01 (SD 3.08) and 0.27 (SD 0.86) at T30 and T60, respectively. Conclusion Methadone used as a first-line opioid therapy provided good analgesia with limited adverse effects and a minimal opioid-induced tolerance

    Summary Sex Hormone-Binding Globulin (SHBG), the plasma carrier for androgens and estradiol, inhibits the estradiolinduced proliferation of breast cancer cells through its membrane receptor, cAMP, and PKA. In addition, the SHBG membrane receptor is preferentially expressed in estrogen-dependent (ER+/PR+) breast cancers which are also characterized by a lower proliferative rate than tumors negative for the SHBG receptor. A variant SHBG with a point mutation in exon 8, causing an aminoacid substitution (Asp 327 → Asn) and thus, the introduction of an additional N-glycosylation site, has been reported. In this work, the distribution of the SHBG variant was studied in 255 breast cancer patients, 32 benign mammary disease patients, and 120 healthy women. The presence of the SHBG mutation was evaluated with PCR amplification of SHBG exon 8 and Hinf I restriction fragment length polymorphism (RFLP) procedure. This technique allowed us to identify 54 SHBG variants (53 W/v and 1 v/v) in breast cancer patients (21.2%), 5 variants (4 W/v and 1 v/v) in benign mammary disease patients (15.6%), and 14 variants (W/v) in the control group (11.6%). The results of PCR and RFLP were confirmed both by nucleotide sequence of SHBG exon 8 and western blot of the plasma SHBG. No differences in the mean plasma level of the protein were observed in the three populations. The frequency of the SHBG variant was significantly higher in ER+/PR+ tumors and in tumors diagnosed in patients over 50 years of age than in the control group. This observation suggests the existence of a close link between the estrogen-dependence of breast cancer and the additionally glycosylated SHBG, further supporting a critical role of the protein in the neoplasm

    Abstract OBJECTIVES: The aim of this study was to evaluate the opioid response in patients receiving morphine and pregabalin, independently from the presumed pain mechanisms, in comparison with patients receiving morphine treatment only. METHODS: A multicenter prospective randomized controlled study was carried out in a sample of 70 advanced cancer patients with pain requiring strong opioids. Thirty-five patients (group MO) were randomized to receive sustained-release morphine using initial doses of 60 mg/day. Thirty-five patients (group MO-PR) were randomized to start the same morphine doses and pregabalin in increasing doses, starting with 25 mg/day up to 150 mg/day in one week. The following data were also recorded before starting the treatments (T0) and then at week intervals for four weeks (W1-4): age, gender, primary cancer and known metastases, pain causes and mechanisms, symptoms associated with opioid therapy, pain intensity, Brief Pain Inventory (BPI), morphine doses and escalation indexes (OEIs), and quality of life. RESULTS: Forty-eight patients completed the study, twenty-eight and sixteen patients in group MO and MO-PR, respectively. Twenty patients were females, the mean age was 65.5 (± 10.3), and the mean Karnofsky status was 66.0 (± 18.9). No differences between groups were found in age (P = 0.839), Karnofsky status (P = 0.741), opioid doses as well as escalation indexes (OEI mg, P = 0.260, and OEI%, P = 0.270). No differences between the two groups were found in quality of life and all BPI items. CONCLUSION: The use of low doses of pregabalin added to morphine therapy in advanced cancer patients does not seem to provide advantageous analgesic effects, despite limitations of the present study due to the number of drop-outs

    BACKGROUND. Cancer pain emergencies presenting with severe excruciating pain require a rapid application of powerful analgesic strategies. The aim of the current study was to evaluate a method of rapid titration with intravenous morphine to achieve relief of cancer pain of severe intensity. METHODS. Forty-nine consecutive patients admitted to a Pain Relief and Palliative Care Unit for severe and prolonged pain were enrolled in the study. Pain was evaluated on a numeric scale of 0-10 (0 indicated no pain and 10 indicated excruciating pain). After the initial assessment (T0), an intravenous line was inserted and boluses of morphine (2 mg every 2 minutes) were given until the initial signs of significant analgesia were detected or severe adverse effects occurred (T1). A continuous reassessment was warranted and the effective total dose administrated intravenously was assumed to last approximately 4 hours and was calculated for 24 hours. The dose immediately was converted to oral morphine (a 1:3 ratio for low doses and a 1:2 ratio for high doses). RESULTS. Data from 45 patients was analyzed. A significant decrease in pain intensity was achieved in a mean of 9.7 minutes (95% confidence interval [95% CI], 7.4-12.1 minutes), using a mean dose of intravenous morphine of 8.5 mg (95% CI, 6.5-10.5 mg). The doses administered rapidly were converted to oral morphine and pain control was mantained until the patient's discharge, which occurred in a mean of 4.6 days (95% CI, 4.1-5.2 days). The incidence of adverse effects was minimal. CONCLUSIONS. The results of the current study demonstrate that cancer pain emergencies can be treated rapidly in the majority of cancer patients with an acceptable level of adverse effects. Intravenous administration of morphine requires initial close supervision and continuity of medical and nursing care. © 2002 American Cancer Society

    Aim: The aim of this prospective study was to determine the characteristics and symptom burden of advanced cancer patients with alcoholism problems and smoking, who were referred to an acute palliative/supportive care unit (ASPCU) of a comprehensive cancer center. Methods: Patientsâ characteristics, indications for admission, kind of admission, awareness of prognosis, and anticancer treatments were recorded. The Edmonton Symptom Assessment Scale (ESAS) was used to assess physical and psychological symptoms, and the CAGE questionnaire for the diagnosis of alcoholism. Patients were also divided in three groups: persistent smokers (PS), former smokers (FS), and non-smokers (NS). The Memorial Delirium Assessment Scale (MDAS) was used to assess the cognitive status of patients. Analgesic drugs and their doses at admission and discharge were recorded, as well opioid escalation index during hospital stay. Results: Three hundred fourteen consecutive cancer patients were surveyed. Forty-seven (14.9%), 143 (45.5%), and 124 (39.5%) subjects were PS-patients, FS-patients, and NS-patients, respectively. Sixteen patients were CAGE-positive. Females were more frequently NS, while males were more frequently FS (p = 0.0005). Statistical differences were also observed in disease awareness among the categories of smoking (p = 0.048). No statistical differences were found in ESAS items, except for drowsiness at T0 in NS-patients. Differences were found in OME and OEI, although the large variability of data did not determined a statistical difference. Higher values of nausea (at T0, p = 0.0005), dyspnea (at T0 and TX, p = 0.08 and 0.023, respectively), and well-being (at TX p = 0.003) were reported in CAGE-positive patients. No correlation was found between CAGE-positive patients and smokers. Conclusion: Although smoking and alcoholism have obvious implications in advanced cancer patients, data remain controversial, as present data did provide limited data to confirm risk factors for advanced cancer patients. Clinical response was not strongly influenced by these risk factors

    The aim of this cohort study is to compare the symptom burden of patients who have an unplanned admission to an acute palliative care unit (APCU) with patients who have a regular planned admission. A consecutive sample of advanced cancer patients who were admitted to an APCU was prospectively assessed. The reasons and the kind of admission were recorded (unplanned, UP, or planned, P). Anticancer treatments, whether patients were on/off treatment or uncertain, previous care setting, and who referred the patient to the unit were also recorded. The Edmonton Symptom Assessment Scale (ESAS) was used at admission and at time of discharge, as well as the Memorial Delirium Assessment Scale. Analgesics and their doses at admission and discharge were recorded. Hospital staying was also recorded. At the time of discharge, subsequent referral to other care settings, and the pathway of oncologic treatment were re-considered. Fifty-five (17.5%) of 314 consecutive admissions recorded in a period of 10 months were UP. UP-patients are more frequently referred from other hospitals (P = 0.0005), and are reported by physicians of other units (P = 0.05). UP-patients have a longer hospital admission (P = 0.032), a higher hospital death rate (P = 0.025), and are less frequently discharged home (P = 0.031). A significant decrease in intensity of ESAS items was observed in both groups, with no differences in symptom burden either at admission and time for discharge. At discharge, opioid doses are higher in UP-patients. An APCU may admit UP-patients at any stage of disease, providing effective treatment outcomes, as reported with P-patients. This study suggests that patients referred from other settings or hospitals may provide specialist advice and rapid symptom control. Although symptom burden is similar, these patients have longer hospital admission, higher hospital death rate, and are less frequently discharged home, suggesting the need for more complex treatments. Such units in a comprehensive cancer center might improve symptom control and pose as referral centers for non-cancer hospitals, emergency departments, or the territory
