Effect of paroxetine hydrochloride (Paxil®) on fatigue and depression in breast cancer patients receiving chemotherapy

SummaryBackground. Fatigue can significantly interfere with a cancer patient’s ability to fulfill daily responsibilities and enjoy life. It commonly co-exists with depression in patients undergoing chemotherapy, suggesting that administration of an antidepressant that alleviates symptoms of depression could also reduce fatigue. Methods. We report on a double-blind clinical trial of 94 female breast cancer patients receiving at least four cycles of chemotherapy randomly assigned to receive either 20 mg of the selective serotonin re-uptake inhibitor (SSRI) paroxetine (Paxil®, SmithKline Beecham Pharmaceuticals) or an identical-appearing placebo. Patients began their study medication seven days following their first on-study treatment and continued until seven days following their fourth on-study treatment. Seven days after each treatment, participants completed questionnaires measuring fatigue (Multidimensional Assessment of Fatigue, Profile of Mood States-Fatigue/Inertia subscale and Fatigue Symptom Checklist) and depression (Profile of Mood States-Depression subscale [POMS-DD] and Center for Epidemiologic Studies-Depression [CES-D]). Results. Repeated-measures ANOVAs, after controlling for baseline measures, showed that paroxetine was more effective than placebo in reducing depression during chemotherapy as measured by the CES-D (p=0.006) and the POMS-DD (p=0.07) but not in reducing fatigue (all measures, ps > 0.27). Conclusions. Although depression was significantly reduced in the 44 patients receiving paroxetine compared to the 50 patients receiving placebo, indicating that a biologically active dose was used, no significant differences between groups on any of the measures of fatigued were observed. Results suggest that modulation of serotonin may not be a primary mechanism of fatigue related to cancer treatment.

Peritoneovenous shunt for palliation of malignant ascites

Forty patients with malignant ascites refractory to conventional medical management had peritoneovenous shunt for palliation. The shunt provided effective palliation in 28 with decrease in weight, abdominal girth, number of paracenteses required and increase in urine output. These patients also had improvement in strength, appetite and ambulation. Complications such as hemodilution, volume overload, and sepsis do not contraindicate surgery. In 12 patients with high ascitic fluid protein content (4.5 g/liter) and a large number of malignant cells, loculated ascites and prior severe renal and cardiac disease, the shunt did not provide palliation. Peritoneovenous shunt appears to provide effective palliation in carefully selected patients with refractory malignant ascites.

Abdominal Involvement at the Onset of Hodgkin's Disease

Abstract One hundred consecutive staging laparotomies were performed in untreated patients with Hodgkins disease without an operative death. Abdominal involvement was documented in each of 16 patients with grossly positive lymphangiograms (clinical stage III). In patients with negative lymphangiograms, 12 of 50 (24 per cent) without symptoms (clinical stages I and IIA) and 16 of 34 (47 per cent) with symptoms (clinical stages I and IIB) were found to have abdominal disease. Of the 44 patients with abdominal involvement, in 15 disease was identified only in the spleen and celiac nodes; in 19 the spleen and paraaortic nodes were involved; and in 5 disease was present in the liver, spleen and paraaortic nodes. In only two patients was abdominal Hodgkins disease restricted to the paraaortic nodes, but in an additional patient involvement was limited to the paraaortic and celiac nodes. One patient had disease in the liver and a common duct node, and another patient had disease in the liver, celiac and paraaortic nodes. Except for a few patients in whom the disease presented in the mediastinum or groin, or with lymphocyte predominance histology, patients with an insignificant risk of abdominal Hodgkins disease could not be identified preoperatively. Neither site of presentation (neck versus axilla, or the right versus the left side of the neck), spleen size, alkaline phosphatase level nor histologic subtype (nodular sclerosis versus mixed cellularity) accurately predicted abdominal disease. Patients with clinical stage I or II Hodgkins disease must either be explored, or treated for abdominal involvement; the need for exploration in patients with clinical stage III disease depends on the treatment plan.

Phase II study of cisplatin for metastatic prostatic carcinoma. An Eastern Cooperative Oncology Group study.

In a phase ii trial 18 previously treated patients with metastatic prostatic carcinoma with measurable or evaluable disease were treated with cisplatin 50 mg/m2 every 3 weeks. Treatment was well tolerated in this elderly group of patients except for GI toxicity seen in 75% of the patients. There were no objective responses. Changes in serum acid phosphatase were often transient and not accompanied by clinical improvement. Cisplatin does not appear to be an effective agent in metastatic prostatic carcinoma in the dose schedule employed.

Septicemia, rash, and pulmonary infiltrates secondary to corynebacterium group JK infection

This report describes a leukemic patient undergoing induction therapy in whom a Corynebacterium JK infection developed while he was leukopenic. The clinical triad of perirectal inflammation, skin lesions, and interstitial lung infiltrates, which has not previously been reported, is discussed. Characteristics of the organism and postulated routes of infection as well as treatment are explored.

Survival of patients with pleural involvement by breast carcinoma

To determine factors which affect survival in patients with pleural involvement by breast carcinoma, we reviewed records of all patients at two community teaching hospitals presenting with malignant pleural effusion over a 6-year period. Forty-five patients had had mastectomy for breast cancer, no history of other malignancy, and cytologic confirmation of subsequent pleural metastases. All had received conventional combination systemic chemo- or hormonal therapy. Ten patients (group 1) in whom effusion was the initial and only site of recurrent disease had a median survival of 48 months. The median survival was 12 months in 35 patients (group 2) who developed effusion in association with other metastatic disease. Half of the patients in group 1 had no axillary node involvement at mastectomy. Twenty-eight patients (80%) in group 2 had had more advanced disease at initial diagnosis. This, and behavior of the effusion as regional rather than systemic disease, suggested by the high incidence of effusion on the ipsilateral side of the mastectomy, probably accounts for the better outlook in patients with effusion alone.

Acute respiratory distress syndrome with pulmonary calcification in two patients with B cell malignancies.

Two patients, one with B cell lymphoma and hypercalcemia and the other with multiple myeloma and hypercalcemia developed acute progressive respiratory insufficiency characteristic of the adult respiratory distress syndrome (ARDS). Both were intubated and placed on mechanical ventilation. Lung compliance deteriorated and became refractory to mechanical inflation. Examination of the lungs at post mortem examination disclosed widespread calcification within alveolar septa and diffuse alveolar damage with hyaline membrane formation consistent with ARDS. Although ARDS has been described with lymphomatous involvement of the lungs, its development in association with metastatic calcification in B cell malignancy has not been previously reported.

A Phase II Study of Carboplatin and CHIP in Patients with Metastatic Colon Carcinoma

Fifty-six patients were treated in each arm of a study comparing CHIP and carboplatin for the therapy of previously untreated metastatic colorectal carcinoma. There were one partial response (2%) with CHIP and two partial responses (4%) with carboplatin. Side effects were significantly more severe with CHIP than with carboplatin. The most common side effect for both drugs was vomiting followed by hematologic side effects. Sixteen percent of the patients receiving CHIP and 9% of those receiving carboplatin had life-threatening side effects. Neither drug offers significant activity in metastatic colorectal carcinoma.

Combination chemotherapy for advanced colorectal cancer. A pilot study

Twenty-three patients with advanced colorectal carcinoma, mostly with liver and lung metastases and measurable disease, were treated with mitomycin-C 20 mg/m2 I.V. and vincristine 1.2 mg/m2 I.V. every 6 weeks, and cisplatinum 50 mg/m2 I.V. and 5-fluorouracil 1,000 mg/m2/24 hours I.V. continuous infusion for 96 hours every 3 weeks based upon the hypothesis that cisplatinum may potentiate the antitumor activity of antimetabolites and alkylating agents. Five patients had received prior chemotherapy and six had received prior radiotherapy, with one of these patients receiving both. One complete and 10 partial responses were observed, with an overall response rate of 48% (90% confidence interval 30–70%). The toxicity was manageable. A possible potentiating effect of cisplatinum is suggested in this first attempt in the treatment of colorectal cancer, and warrants further exploration.

Preoperative radiation therapy with sensitizers in the management of carcinoma of the rectum.

There is enough evidence to show that adjuvant radiation therapy contributes to the management of patients with carcinoma of the rectum. In an effort to improve resectability and possibly survival rates, the use of chemosensitizers, combined with moderate doses of radiation used presurgically, was introduced for carcinomas larger than 5 cm in diameter requiring abdominoperineal resection. Based on our experience and that of others, it is believed that the method of administration of 5FU and mitomycin-C is an important factor in obtaining an increased therapeutic ratio. Because of the locoregional pattern of spread of rectal cancer, this adjuvant approach would appear suitable. A series of approximately 60 patients is discussed and the surgical findings and five-year survival is reported.
