Side effects of cisplatin and carboplatin include nausea, vomiting, peripheral neuropathy, nephrotoxicity, hearing loss, bone marrow depression, and rarely Lhermitte's sign and allergic reactions. A unique case of idiosyncrasy related to carboplatin administration was observed in a young woman treated for ovarian cancer. Symptoms and signs included skin rash, shortness of breath, and redness of face and upper trunk, without drop in blood pressure or change in heart rate, and were resolved within a short time following administration of hydrocortisone and promethazine.

This study was performed to determine the clinical activity and safety of paclitaxel in the treatment of patients with refractory or relapsing aggressive Non-Hodgkin's lymphoma (NHL). Between May 3, 1994 and February 16, 1996, 39 patients with refractory or relapsing NHL consented to be enrolled in two, multicenter, open-labelled studies to evaluate the efficacy, safety, time to progression and overall survival of paclitaxel given at a dose of 175 mg/m2 by a 3-hour IV infusion every three weeks without G-CSF use. Data from the two studies is combined. One patient, although registered, did not receive treatment. Of the remaining 38 patients, 17 men and 21 women aged 26-82 years (median 60) were given 104 courses of paclitaxel [median 2 (range 1-6)]. Seventeen patients had stage IV, 7 stage III, 8 stage II, 5 stage 1 and 1 unknown stage of disease. Histologic grades included 1 low, 33 intermediate, and 4 high. Three patients had bone marrow involvement. Median time from diagnosis to study entry was 19 months (1-160). The median number of previous chemotherapy regimens was 2 (range 1-6). Three of the 35 (8.6%) patients evaluable for response had partial remission (PR) of their disease for 1-7 months (median 2) and 11/35 (31.4%) stable disease (SD) for 1 to 19 months (median 3). All three responders and 3 of the 11 SD patients had received paclitaxel after relapsing from a CR. At analysis, nine of the 38 patients were alive. Median duration of follow up at analysis was 6 months (3 days-29 months). The estimated survival rates for all patients at 1 and 2 years are 34% and 27%, respectively (Kaplan-Meier) from the start of paclitaxel treatment. The median survival time was 5.4 months (3 days to 28+ months). Febrile neutropenia occurred in two patients. Seven (18%) patients developed a neutrophil nadir of < 0.5 x 10(9)/L and 2 (5%) patients developed a platelet nadir of < 50 x 10(9)/L. Six patients received blood transfusions. Non-hematologic toxicity was generally mild to moderate with all patients experiencing some toxicity. Twenty-seven patients experienced grade III toxicity including: alopecia (n = 19), pain (n = 9), fatigue (n = 5), nausea/vomiting (n = 3), diarrhoea (n = 2), pulmonary/shortness of breath (n = 2), anorexia (n = 1) and fluctuating levels of consciousness and somnolence (n = 1). Two patients experienced grade IV toxicity (infection, peripheral neuropathy, pain). No patient discontinued paclitaxel for a severe hypersensitivity reaction. In summary, administered as a 3-hour infusion, paclitaxel 175 mg/m2 results in mild myelotoxicity but minimal antitumor activity in patients with refractory NHL.

Docetaxel (Taxotere) is one of the most active new generation chemotherapy agents against advanced non-small cell lung cancer (NSCLC). This study aimed to determine the activity, toxicity and impact on the quality of life (QOL) in patients treated with docetaxel after failure with first-line platinum-based combination chemotherapy. Twenty-one patients with advanced NSCLC who had previously received the platinum-containing regimen were treated with docetaxel 75 mg/m2 every 3 weeks. QOL was assessed at intervals during the treatment period using the Functional Assessment of Cancer Treatment - Lung (FACT-L). Of the 21 patients enrolled, 16 were able to be evaluated for response and 20 were included in the toxicity analysis. The median age was 57 (range, 39-75 years). A median of 3 cycles was given (range, 1-9). Of the 16 evaluatable patients, there was one partial response (6.3%) and 4 with stable disease (25%). The median survival time was 8.1 months and the 1-year survival rate was 25%. Myelosuppression and peripheral neuropathy were the major toxicities. Grade 3/4 neutropenia and paresthesia occurred in 6 patients (30%) and 3 patients (15%), respectively. There was no significant improvement or deterioration in the overall FACT-L, TOI (Trial Outcome Index) and lung cancer symptom scores during the treatment. Symptom improvement was noted, in particular for shortness of breath and weight loss in the majority of patients. It is concluded that docetaxel is a well tolerated second-line treatment for recurrent NSCLC. Of particular importance was that the treatment did not negatively impact the overall quality of life, on the contrary, did palliate some of the lung cancer related dash symptoms in many patients.

In order to examine the efficacy and safety of nanoparticle albumin-bound paclitaxel (nab-P) in combination with bevacizumab (B) and gemcitabine (G) for the first-line treatment of patients with HER2-negative metastatic breast cancer (MBC). In this single-center, open-label phase II trial, patients with HER2-negative MBC received gemcitabine 1500 mg/m(2), nab-paclitaxel 150 mg/m(2), and bevacizumab 10 mg/kg (each administered intravenously) on days 1 and 15 of a 28-day cycle. The primary end point was progression free survival (PFS); secondary end points were overall response rate (ORR), complete (CR) and partial (PR) response rates, clinical benefit (ORR + stable disease), overall survival (OS), and safety. Thirty patients were enrolled. One patient was ineligible and was not included in analysis. Median PFS was 10.4 months (95% CI: 5.6-15.2 months). ORR was 75.9%, comprising eight (27.6%) CRs and 14 (48.3%) PRs; five patients had stable disease (SD) and two patients (6.9%) had progressive disease (PD) as their best response. The clinical benefit rate was 93.1% (27/29) in the overall group and 84.6% in the triple-negative cohort (11/13). The 18-month survival rate was 77.2% (95% CI: 51.1-90.5%). Eight (27.6%) patients experienced grade 3 or 4 toxicity: grade 4 neutropenic fever (n = 1) and grade 3 infection (n = 6), leukopenia, thrombocytopenia, peripheral neuropathy, seizure, shortness of breath, hematuria, and cardiac tamponade (one each). First-line therapy with nab-P, B, and G demonstrated a median PFS of 10.4 months and a 75.9% ORR with acceptable toxicity; this novel combination warrants investigation in a randomized study.

We report the fourth case of transthyretin amyloidosis (ATTR) Ser23Asn in a 41-year-old Ecuadorian male. He has a pedigree that spans seven generations and involves 24 family members who suffered early cardiac death. Salient presenting symptoms were fatigue, shortness of breath, and peripheral neuropathy. The diagnosis of cardiac amyloid was confirmed by immunohistochemical staining of an endomyocardial biopsy, genotyping and by technetium pyrophosphate ((99m)Tc-PYP) scintigraphy, which remains to be established as a reliable tool to visualize myocardial amyloid involvement in patients with the Ser23Asn transthyretin (TTR) variant. The patient underwent successful combined heart and liver transplant. We add to the current ATTR literature that in patients with the rare Ser23Asn mutation, peripheral nerve in addition to cardiac involvement can occur and (99m)Tc-PYP scintigraphy can be used as an imaging modality to visualize myocardial amyloid.

A 41-year-old Hispanic woman with a 20 pack-year smoking history presented with worsening shortness of breath on exertion that gradually started 2 years ago, then significantly deteriorated over the last 4 months. She was diagnosed with COPD 2 months prior to her presentation and started on treatment with fluticasone propionate and albuterol. Her medical history was relevant for undifferentiated connective tissue disorder diagnosed 5 years prior due to a positive antinuclear antibody test, arthralgia, recurrent urticarial skin rash, peripheral neuropathy, abdominal pain, and diffuse body swelling. She was started on treatment with prednisone and azathioprine at the time and had substantial improvement in the occurrence of her urticaria. She also had a history of recurrent laryngeal edema of unclear etiology. She had no history of IV drug abuse, no exposure to animals, was not sexually active, and had no recent travel outside of Florida. There was no significant family history of lung diseases.

The hallmark signs and symptoms of anemia are directly related to a decrease in oxygen delivery to vital tissues and organs and include pallor, fatigue, lightheadedness, and shortness of breath. Neurologic complications are often nonspecific and can include poor concentration, irritability, faintness, tinnitus, and headache. If undiagnosed or untreated, anemia can progress to cognitive dysfunction, psychosis, encephalopathy, myelopathy, peripheral neuropathy, and more focal syndromes, such as stroke, seizures, chorea, and transverse myelitis. Imaging can play an important role in the early diagnosis and treatment of these neurologic and systemic complications associated with anemia, and hence, better outcome.
