RESUMEN

BACKGROUND: This study examined surgical trends for oropharynx squamous cell carcinoma (OPC) from 1998 to 2012, with a post-2009 focus coinciding with the Food and Drug Administration (FDA) approval of transoral robotic surgery (TORS). METHODS: Using the National Cancer Data Base, the study analyzed 84,449 patients with stage I-IVB OPC. χ (2) tests and logistic regression models were used to examine surgical trends. RESULTS: The use of surgery decreased from 41.4 % in 1998 to 30.4 % in 2009 (p < 0.001). The surgical trends reversed and in 2012 increased to 34.8 % (p < 0.001). There was much variation in surgery in 2012 between American Joint Committee on Cancer stages, with 80.2 % of stage I patients receiving surgery compared with 54.0 % of stage II patients, 36.8 % of stage III patients, and 28.5 % of stage IV patients (p < 0.001). Black patients with high socioeconomic status (SES) showed lower use of surgery (25.3 %) compared to low SES white (32.3 %) and low SES Hispanic patients (27.3 %) (p < 0.001). The highest surgical rates were noted in the West North Central region and lowest rates were observed in the New England and South Atlantic regions. Between 2009 and 2012, independent predictors of surgical treatment included young age, female gender, white or Hispanic race, high SES, private insurance, academic hospitals, hospitals in the West North Central region, residence more than 75 miles from the hospital, increasing comorbidities, stage I disease, and tonsil origin (all p < 0.05). CONCLUSION: Since FDA approval of TORS in 2009, surgical rates have increased with multiple socioeconomic and regional factors affecting patient selection. This study provides a basis for further investigation into factors involved in decision making for OPC patients.

RESUMEN

Cancer-associated thrombosis (CAT) is common and associated with mortality. We estimated CAT rate by cancer sites and inherited factors among cancer patients from the UK Biobank (N =70,406). The 12-month CAT rate after cancer diagnosis was 2.37% overall but varied considerably among cancer sites. Among the 10 cancer sites classified as 'high-risk' of CAT by the National Comprehensive Cancer Network guidelines, 6 had CAT rate <5%. In contrast, 5 cancer sites classified as 'average-risk' by the guidelines had CAT rate >5%. For inherited risk factors, both known mutation carriers in two genes (F5/F2) and polygenic score for venous thromboembolism (VTE) (PGSVTE) were independently associated with increased CAT risk. While F5/F2 identified 6% patients with high genetic-risk for CAT, adding PGSVTE identified 13 % patients at equivalent/higher genetic-risk to CAT than that of F5/F2 mutations. Findings from this large prospective study, if confirmed, provide critical data to update guidelines for CAT risk assessment.

RESUMEN

To evaluate the performance characteristics of PD-L1 immunohistochemistry (IHC) combined positive scoring (CPS) in core biopsies and aspirate cell blocks from patients with head and neck squamous cell carcinoma (HNSqCCa). PD-L1 IHC using the SP263 antibody was performed on 20 paired cases which consisted of a small biopsy and an excisional specimen. The scores were compared at both the 1% and 20% cutpoints. Using the CPS result obtained from the resected specimen or excisional biopsy as the gold standard, PD-L1 IHC performed on the core biopsy or cell block identified 4 of 6 positive cases (66%) at the 20% cutpoint and 12 of 17 (70%) positive patients at the 1% cutpoint. False positive cases were uncommon at both cutpoints. CPS scoring should be used with caution in small biopsies from patients with HNSqCCa. A negative result should prompt consideration of an excisional biopsy and repeat testing.

RESUMEN

Importance: A proactive speech and language pathology (SLP) program is an important component of the multidisciplinary care of patients with head and neck squamous cell carcinoma (HNSCC). Swallowing rehabilitation can reduce the rate of feeding tube placement, thereby significantly improving quality of life. Objective: To evaluate the initiation of a proactive SLP rehabilitation program at a single institution and its association with rates of feeding tube placement and dietary intake in patients with HNSCC. Design, Setting, and Participants: Cohort study at a tertiary care and referral center for patients with HNSCC serving the northern Chicago region. Patients were treated for squamous cell carcinomas of the hypopharynx, oropharynx, and nasopharynx from 2004 to 2015 with radiation or chemoradiation therapy in the definitive or adjuvant setting. Patients who received less than 5000 cGy radiation or underwent reirradiation were excluded. Interventions: A proactive SLP program for patients with HNSCC was initiated in 2011. Study cohorts were divided into 2 groups: 2004 through 2010 and 2011 through 2015. Main Outcomes and Measures: Primary outcome variables were SLP referral placement and timing of the referral. Secondary outcomes were feeding tube placement and ability to tolerate any oral intake. Results: A total of 254 patients met inclusion criteria (135 before and 119 after implementation of SLP program; median age, 60 years [range, 14-94 years]; 77% male). With the initiation of a proactive SLP program, pretreatment evaluations increased from 29 (21.5%) to 70 (58.8%; risk ratio [RR], 2.74; 95% CI, 1.92-3.91), and rate of referral overall at any time increased from 60.0% to 79.8% (RR, 1.33; 95% CI, 1.13-1.57). Feeding tube placement rates decreased from 45.9% (n = 62) to 29.4% (n = 35; RR, 0.64; 95% CI, 0.46-0.89). Among patients receiving a swallow evaluation, feeding tube requirements were less frequent for those receiving a pretreatment evaluation (31 of 99 [31%]) than for those referred during (11 of 18 [61%]) or after (38 of 59 [64%]) treatment. The rate of tolerating any oral intake at the end of treatment improved from 71.1% (n = 96) in the preimplementation period to 82.4% (n = 98; RR, 1.16; 95% CI, 1.01-1.33). Conclusions and Relevance: A proactive SLP program can be successfully established as part of the multidisciplinary care of patients with HNSCC and improve patient quality of life.

RESUMEN

PURPOSE: An objective response rate of 11% was reported in patients with recurrent and/or metastatic squamous cell carcinoma of the head and neck (SCCHN) treated with 500 mg daily gefitinib although the recommended dose in lung cancer is 250 mg. This study evaluated the efficacy and toxicity of 250 mg daily gefitinib in patients with recurrent and/or metastatic SCCHN. EXPERIMENTAL DESIGN: Phase II trial with objective response rate as the primary end point. Measurements of quality of life and levels of serum vascular endothelial growth factor and transforming growth factor-alpha were assessed before and during therapy. RESULTS: In 70 patients, 1 (1.4%) partial response was observed. Median progression-free survival and overall survival were 1.8 and 5.5 months, respectively. Quality of life scores improved transiently during the first weeks of therapy before returning to baseline. Median vascular endothelial growth factor and transforming growth factor-alpha levels were above the normal range but were not predictive of outcome. Four patients experienced grade 3 drug-related adverse events. Rash of any grade was observed in 64% of subjects. Correlation between disease control (partial response + stable disease), progression-free survival, and overall survival and grade of cutaneous toxicity was observed (P = 0.001, 0.001, and 0.008 respectively). CONCLUSIONS: Gefitinib monotherapy at 250 mg in recurrent and/or metastatic SCCHN seems to have less activity than was previously observed for 500 mg daily. A dose-response relationship may exist for this agent in SCCHN and grade of cutaneous toxicity attributable to gefitinib is a clinical predictor of better outcome.

RESUMEN

INTRODUCTION: As epidermal growth factor receptor (EGFR) is overexpressed in approximately 90% of squamous cell carcinomas of the head and neck (SCCHN), several therapeutic agents that target EGFR have been evaluated for the treatment of SCCHN. Although patients with SCCHN derive clinical benefit from anti-EGFR agents, most notably the EGFR monoclonal antibody cetuximab, these patients eventually become resistant to EGFR-based therapies; preclinical studies have shown activation of secondary signaling pathways that lead to resistance to EGFR inhibition and, as such, serve as potential therapeutic targets to overcome resistance to EGFR inhibitors. AREAS COVERED: This review summarizes the results of recently completed trials of anti-EGFR agents in SCCHN, highlights the various mechanisms that drive resistance to EGFR inhibitors in SCCHN, and focuses on several novel targeted agents that could potentially help overcome resistance to EGFR-based therapies in SCCHN. Expert commentary: Due to the development of resistance to EGFR-targeted therapies, novel treatment approaches to overcome resistance are a key unmet need for SCCHN.

RESUMEN

Anti-Programed Death 1 (PD-1) is standard immunotherapy for multiple cancers, and the expression of one of its ligands, PD-L1, has been described in germ cell tumors (GCT). Neither the clinical activity of anti-PD-1 nor the incidence of an immunoresponsive tumor microenvironment has been described for GCTs. A patient initially diagnosed with melanoma via fine needle aspiration was treated with one dose of antibody to PD-1. A core needle biopsy was subsequently performed to acquire sufficient tissue for molecular analysis, which led to a change in diagnosis to metastatic embryonal carcinoma. The testicular GCT cohort of The Cancer Genome Atlas was analyzed using a T-cell gene signature associated with benefit from immunotherapy. Primary tumors (N = 134) were categorized as high (T-cell-inflamed), medium, or low (non-T-cell-inflamed) by their T-cell signature derived from RNAseq data. Anti-PD-1 induced decreases in serum markers and a 33% reduction in tumor volume. Gene expression revealed a T-cell-inflamed tumor microenvironment in 47% of testicular GCTs, including seminoma (83%) and nonseminoma (17%) tumor subtypes. Expression of alpha-fetoprotein (AFP) RNA correlated with lack of the T-cell signature, with increasing AFP RNA inversely correlating with the inflamed signature and expression of IFNγ-associated genes. These data suggest that GCTs can respond to anti-PD-1 and that gene expression profiling supports investigation of immunotherapy for treatment of GCTs. Cancer Immunol Res; 4(11); 903-9. ©2016 AACR.

RESUMEN

PURPOSE: The paclitaxel, fluorouracil, and hydroxyurea regimen of paclitaxel, infusional fluorouracil, hydroxyurea, and twice-daily radiation therapy (TFHX) administered every other week has resulted in 3-year survival rates of 60% of stage IV patients. Locoregional and distant failure rates were 13% and 23%, respectively. To reduce distant failure rates, we added a brief course of induction chemotherapy to TFHX. PATIENTS AND METHODS: Sixty-nine patients received six weekly doses of carboplatin (AUC2) and paclitaxel (135 mg/m2) followed by five cycles of TFHX. RESULTS: Ninety-six percent had stage IV disease. Response to induction chemotherapy was partial response 52% and complete response (CR) 35%. Symptomatically, there was a significant reduction in mouth and throat pain. The most common grade 3 or 4 toxicity was neutropenia (36%). Best response following completion of TFHX was CR in 83%. Toxicities of TFHX consisted of grade 3 or 4 mucositis (74% and 2%) and dermatitis (47% and 14%). At a median follow-up of 28 months, locoregional or systemic disease progression were each noted in five patients. The overall 3-year progression-free survival was 80% (95% confidence interval [CI], 71% to 90%), and the 2- and 3-year overall survival rates were 77% (95% CI, 66% to 87%) and 70% (95% CI, 59% to 82%), respectively. At 12 months, five patients were completely feeding-tube dependent. CONCLUSION: Administration of carboplatin and paclitaxel before TFHX chemoradiotherapy results in high response activity and may decrease distant failure rates. Overall survival, progression, and organ preservation/functional outcome data support definitive evaluation of this approach.

RESUMEN

PURPOSE: The purpose of this retrospective analysis was to evaluate the emergence of second primary malignancies and the contribution of different causes of death to the outcome of patients with locoregionally advanced head and cancer receiving primary chemoradiotherapy. EXPERIMENTAL DESIGN: We studied 324 patients with stage IV squamous cell head and neck cancer who were enrolled on five consecutive multicenter Phase II studies of concurrent chemoradiotherapy. All of the regimens included concurrent 5-fluorouracil and hydroxyurea on an alternate week schedule with radiotherapy, either alone (FHX) or with cisplatin (C-FHX) or paclitaxel (T-FHX). The cumulative incidence of second primary tumors or death from any cause was estimated using methods of competing risk analysis. RESULTS: Median follow-up of surviving patients was 5.2 years (2-10.6 years). The 5-year overall survival and progression-free survival of the cohort were 46% and 65%, respectively. Causes of death and median time of occurrence were as follows: disease (n = 88; 1.5 years), treatment-associated acute or late complications (n = 30; 4 months), second primary tumors (n = 18; 3.5 years), comorbidities (n = 41; 1.9 years), and unknown (n = 20; 5.1 years). Predominant causes of death from comorbidities were cardiac and respiratory illnesses. Twenty-six patients (8%) developed a second primary tumor at a median time of 2.8 years (4 months to 10 years). The cumulative incidence of second primary tumors was 5%, 7%, and 13% at 3, 5, and 10 years, respectively. The most frequent site of second primaries was the lung (n = 13), followed by the esophagus (n = 3) and head and neck (n = 2) CONCLUSIONS: Patients with locoregionally advanced head and neck cancer treated with concurrent chemoradiotherapy are potentially curable but face significant risks of mortality from causes other than disease progression. Ameliorating toxicity, and implementing secondary screening and chemoprevention strategies are major goals in the management of head and neck cancer.

RESUMEN

PURPOSE: Induction chemotherapy with carboplatin and paclitaxel followed by concomitant TFHX (paclitaxel, infusional 5-fluorouracil, hydroxyurea, and twice-daily radiation therapy administered every other week) has resulted in 70% 3-year survival in stage IV patients. Locoregional and distant control rates were 94 and 93%, respectively. In an attempt to decrease toxicity without compromising local control, a second cohort of patients was treated with a lower dose of radiation to sites of potential microscopic disease. EXPERIMENTAL DESIGN: Sixty-four patients were entered on study. Patients received six weekly doses of carboplatin (area under the curve 2) and paclitaxel (135 mg/m2) followed by five cycles of TFHX. The radiation dose to gross disease was 75 Gy as in the previous trial. The radiation dose to high-risk microscopic disease was reduced from 60 to 54 Gy, and the dose to low-risk microscopic disease was reduced from 45 to 39 Gy. RESULTS: Ninety-seven percent of patients had stage IV disease. The response rate to induction chemotherapy was 82% with a complete response rate of 42%. At the completion of therapy the clinical complete response rate rose to 100% with a median follow-up of 29 months. The actuarial 2 and 3-year survival was 77 and 70%, respectively. Five patients developed progressive disease for an overall 3-year progression-free survival of 90%. Two patients failed in locoregional sites alone, resulting in a 3-year locoregional control of 97%. The 3-year systemic control was 95%. Four patients were completely feeding tube dependent at the time of analysis. Only 1 of these patients had normal swallowing function before treatment. CONCLUSIONS: In this second trial, induction chemotherapy with carboplatin and paclitaxel followed by TFHX chemoradiotherapy results in high survival and progression-free survival. The reduction in radiation dose did not compromise survival or disease control compared with our prior study using higher radiation doses. Data continues to support definitive evaluation of this approach.

RESUMEN

PURPOSE: To expand on our experience with the combination of paclitaxel, fluorouracil, hydroxyurea, and twice daily irradiation (T-FHX) and to assess the impact of weekly administration of erythropoietin (r-HuEpo) on transfusion requirements, we conducted a Phase II multi-institutional trial with a simplified 1-h paclitaxel infusion schedule and randomized patients to receive weekly doses of r-HuEpo. PATIENTS AND METHODS: A total of 90 patients with locally advanced head and neck cancers (stage IV, 96%; N(2)/N(3), 66%) were treated on a regimen of 1-h infusion of paclitaxel (100 mg/m(2)/day, day 1), 120-h infusion of 5-fluorouracil (600 mg/m(2)/day, days 0-5); hydroxyurea 500 mg p.o. every 12 h for 11 doses; and radiation 150cGy bid, days 1-5 of each 14-day cycle repeated for five cycles over 10 weeks (7200-7500 cGy). Before initiating therapy, patients were randomized to receive r-HuEpo 40,000 IU s.c. once weekly. RESULTS: At median follow-up of 40 months, 3-year progression-free survival is 62%, locoregional control is 84%, and systemic control is 79%. Overall survival is 59%. Anemia, leucopenia, dermatitis, and mucositis were the most frequent grade 3 or 4 toxicities. Patients randomized to erythropoietin experienced less grade 2/3 anemia (52 versus 77%; P = 0.02), but transfusion requirements were not significantly different. CONCLUSIONS: T-FHX is an active and tolerable regimen inducing local tumor control and promising survival with organ preservation in high-risk patients. One h infusion of paclitaxel simplified the regimen without compromising efficacy. Addition of erythropoietin does not reduce the need for transfusion with this nonplatinum-containing regimen. T-FHX should be advanced to a randomized trial and compared with a cisplatin-based concomitant regimen.

RESUMEN

Docetaxel has demonstrated activity in a broad range of solid tumors. Phase I trials have shown 100 mg/m(2) every 21 d to be the recommended dose. This phase I trial was designed to define the dose-limiting toxicities (DLTs) and maximum tolerated dose (MTD) of docetaxel with granulocyte colony-stimulating factor (G-CSF) support in patients with advanced solid tumors. Eligible patients had advanced malignancies and up to two prior chemotherapy regimens, ECOG PS = 0 1, adequate organ function, and gave written, informed consent. Docetaxel was escalated in cohorts of patients starting at 100 mg/m(2) on a 21-d schedule. Prophylactic G-CSF was administered on d 3 10. The DLT was defined as grade IV neutropenia >4 d, febrile neutropenia, grade IV thrombocytopenia, any grade III nonhematologic toxicity, or the inability to receive cycle 2 because of ongoing toxicity. Twenty-three patients were enrolled at doses up to 145 mg/m(2). The median age was 59 yr and the median number of prior chemotherapy regimens was 1. No DLT was observed at 100 mg/m(2), and 2 of 11 patients at 120 mg/m(2) experienced DLT (neutropenic fever and stomatitis). At 145 mg/m(2), one of eight patients had DLT (fatigue). Two of eight patients at 145 mg/m(2) had brief grade IV neutropenia (without fever), and none had grade III-IV thrombocytopenia or anemia. The docetaxel dose can be safely escalated to 145 mg/m(2) every 21 d with GCSF support, a 45% increase above the standard recommended phase II dose. Further studies will clarify the role of dose-intensified docetaxel.

RESUMEN

PURPOSE: Induction chemotherapy (IC) before radiotherapy lowers distant failure (DF) rates in locally advanced squamous cell carcinoma of the head and neck (SCCHN). The goal of this phase III trial was to determine whether IC before chemoradiotherapy (CRT) further improves survival compared with CRT alone in patients with N2 or N3 disease. PATIENTS AND METHODS: Treatment-naive patients with nonmetastatic N2 or N3 SCCHN were randomly assigned to CRT alone (CRT arm; docetaxel, fluorouracil, and hydroxyurea plus radiotherapy 0.15 Gy twice per day every other week) versus two 21-day cycles of IC (docetaxel 75 mg/m(2) on day 1, cisplatin 75 mg/m(2) on day 1, and fluorouracil 750 mg/m(2) on days 1 to 5) followed by the same CRT regimen (IC + CRT arm). The primary end point was overall survival (OS). Secondary end points included DF-free survival, failure pattern, and recurrence-free survival (RFS). RESULTS: A total of 285 patients were randomly assigned. The most common grade 3 to 4 toxicities during IC were febrile neutropenia (11%) and mucositis (9%); during CRT (both arms combined), they were mucositis (49%), dermatitis (21%), and leukopenia (18%). Serious adverse events were more common in the IC arm (47% v 28%; P = .002). With a minimum follow-up of 30 months, there were no statistically significant differences in OS (hazard ratio, 0.91; 95% CI, 0.59 to 1.41), RFS, or DF-free survival. CONCLUSION: IC did not translate into improved OS compared with CRT alone. However, the study was underpowered because it did not meet the planned accrual target, and OS was higher than predicted in both arms. IC cannot be recommended routinely in patients with N2 or N3 locally advanced SCCHN.

RESUMEN

Head and neck squamous cell carcinoma (HNSCC) is a major cause of morbidity and mortality underscoring the need for safe and effective chemopreventive strategies. Targeting epidermal growth factor receptor (EGFR) is attractive in that it is an early critical event in HNSCC pathogenesis. However, current agents lack efficacy or have unacceptable toxicity. Several groups have demonstrated that the over-the-counter medication, polyethylene glycol (PEG) has remarkable chemopreventive efficacy against colon carcinogenesis. Importantly, we reported that this effect is mediated through EGFR internalization/degradation. In the current study, we investigated the chemopreventive efficacy of this agent against HNSCC, using both the well validated animal model 4-NQO (4-nitroquinoline 1-oxide) rat model and cell culture with the human HNSCC cell line SCC-25. We demonstrated that daily topical application of 10% PEG-8000 in the oral cavity (tongue and cavity wall) post 4NQO initiation resulted in a significant reduction in tumor burden (both, tumor size and tumors/tumor bearing rat) without any evidence of toxicity. Immunohistochemical studies depicted decreased proliferation (number of Ki67-positive cells) and reduced expression of EGFR and its downstream effectors cyclin D1 in the tongue mucosa of 4NQO-rats treated with PEG. We showed that EGFR was also markedly downregulated in SCC-25 cells by PEG-8000 with a concomitant induction of G1-S phase cell-cycle arrest, which was potentially mediated through upregulated p21(cip1/waf1). In conclusion, we demonstrate, for the first time, that PEG has promising efficacy and safety as a chemopreventive efficacy against oral carcinogenesis.

RESUMEN

The incidence of squamous cell carcinoma of the head and neck (SCCHN) is on the rise in the US despite a drop in cigarette smoking rates. Much of this rise is due to the increasing incidence of SCCHN attributable to human papillomavirus (HPV). HPV-related SCCHN has a high cure rate, which contributes to the stable death rates despite the increased incidence. Up to half of patients with SCCHN will develop recurrence. For these patients, the first clinical decision is whether the recurrence is potentially treatable for cure, or is incurable. For those deemed potentially curable, surgical or radiation-based therapies, or both, are undertaken. For those who have incurable recurrences, the goals are palliation and possibly prolongation of life - average survivals are in the range of 6-12 months depending on the type of recurrence and other factors. Several chemotherapy drugs are active in SCCHN, most notably the platinum compounds, taxanes, fluorouracil (5-FU), methotrexate and cetuximab. Approximately 10-25% of patients will respond to treatment with one of these drugs. The response rate is higher for combinations such as a platinum plus a taxane, a platinum plus 5-FU, a combination of the three, or one of more of these drugs plus cetuximab. Combination chemotherapy has not been shown to prolong survival over single-agent therapy, with the exception of the addition of cetuximab to a platinum and 5-FU combination. A number of orally bioavailable tyrosine kinase inhibitors have been tested or are undergoing trials in SCCHN. None of these has as yet been shown to be more effective than the currently available drugs. For patients with recurrences who are undergoing active therapy, and especially for those for whom further therapy is no longer appropriate or is declined, strict attention is necessary to palliation of pain, oral and airway issues, and to nutrition, speech, and social and psychological issues.

RESUMEN

Outcomes for patients with oropharyngeal cancer are determined by their tumor characteristics and associated demographics. The role of human papilloma virus-related disease for prognosis and outcomes with chemoradiotherapy is being more clearly defined. EGFR inhibitors are used in conjunction with radiotherapy, and the importance of optimizing radiation quality and minimizing toxicity is the focus of ongoing studies.

RESUMEN

PURPOSE: Computerized physician order entry (CPOE) in electronic health records (EHR) has been recognized as an important tool in optimal health care provision that can reduce errors and improve safety. The objective of this study is to describe documentation completeness and user satisfaction of medical charts before and after implementation of an outpatient oncology EHR/ CPOE system in a hospital-based outpatient cancer center within three treatment sites. METHODS: This study is a retrospective chart review of 90 patients who received one of the following regimens between 1999 and 2006: FOLFOX, AC, carboplatin + paclitaxel, ABVD, cisplatin + etoposide, R-CHOP, and clinical trials. Documentation completeness scores were assigned to each chart based on the number of documented data points found out of the total data points assessed. EHR/CPOE documentation completeness was compared with completeness of paper charts orders of the same regimens. A user satisfaction survey of the paper chart and EHR/CPOE system was conducted among the physicians, nurses, and pharmacists who worked with both systems. RESULTS: The mean percentage of identified data points successfully found in the EHR/CPOE charts was 93% versus 67% in the paper charts (P < .001). Regimen complexity did not alter the number of data points found. The survey response rate was 64%, and the results showed that satisfaction was statistically significant in favor of the EHR/CPOE system. CONCLUSION: Using EHR/CPOE systems improves completeness of medical record and chemotherapy order documentation and improves user satisfaction with the medical record system. EHR/CPOE requires constant vigilance and maintenance to optimize patient safety.

RESUMEN

Basal cell carcinoma (BCC) is usually a benign and indolent cancer cured in greater than 95 percent of cases. Nevertheless, it can be locally destructive or occasionally metastasize to distant organs. We report a case of BCC metastatic to the lungs, occurring 17 years after the primary BCC was noticed, that responded to carboplatin and paclitaxel on 3 occasions. The patient also developed pure red cell aplasia (PRCA). Work-up did not reveal underlying thymoma or infectious, rheumatologic, or lymphoproliferative disorders. Parvovirus serologies were negative, and antibodies against erythropoetin were not detected. There was no history of exposure to drugs associated with PRCA. Bone marrow biopsy on 2 different occasions did not show evidence of myelodysplasia. PRCA may represent an unusual paraneoplastic syndrome associated with BCC as reported with other carcinomas. This is the first report of PRCA associated with metastatic BCC or the drugs carboplatin and paclitaxel, which were used to treat it. The literature on chemotherapy for metastatic BCC is reviewed.
