  ABSTRACT: 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.

  ABSTRACT: 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. 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. 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. 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.

  ABSTRACT: 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.

  ABSTRACT: 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. 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. 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). 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.

  ABSTRACT: The purpose of this study was to evaluate the role of neck lymph node (ND) in the combined dissection modality therapy for locoregionally advanced head and neck. We identified patients with N2-N3 head and neck cancers who were enrolled in three consecutive multicenter phase II studies of concurrent chemoradiotherapy utilizing 5-fluorouracil and hydroxyurea on an alternate-week schedule with radiotherapy twice daily plus either cisplatin (C-FHX) or paclitaxel (T-FHX). Patients with unknown primary tumors, nasopharyngeal or paranasal sinus primaries, nonsquamous histology, progression or death during therapy, or incomplete therapy were excluded. A total of 131 patients were analyzed. Seventy-nine percent had N2 stage. ND was performed in 92 patients (70%), either prior to enrollment (n = 31) or after chemoradiotherapy (n = 61). With a median follow-up of 4.6 years, the 5-year locoregional and neck progression-free survival (PFS) rates were higher in patients with ND versus patients without ND: 88% versus 74% (p =.02) and 99% versus 82% (p =.0007). respectively; there was also a trend toward improved overall survival (OS) with ND, but PFS and distant PFS were comparable. In the subset of patients with N3 disease, ND was associated not only with better locoregional control but also with improved distant PFS. However, in patients with clinical complete response (n = 92), no significant differences in PFS (68% vs 75% at 5 years, p =.53) or any other survival parameters with or without ND were observed. ND improves neck control and is required for patients with clinically residual disease or N3 neck cancer but has no significant impact on the outcome of patients with N2 stage disease who are rendered clinically disease-free with intensive concurrent chemoradiotherapy.

  ABSTRACT: 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. 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. 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) 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.

  ABSTRACT: 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. 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. 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. 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.

  ABSTRACT: Prior research has suggested that patients who travel out of their neighborhood for elective care from specialized medical centers may have better outcomes than local patients with the same illnesses who are treated at the same centers. We hypothesized that this phenomenon, often called "referral bias" or "distance bias," may also be evident in curative-intent cancer trials at specialized cancer centers. We evaluated associations between overall survival and progression-free survival and the distance from the patient residence to the treating institution for 110 patients treated on one of four phase II curative-intent chemoradiotherapy protocols for locoregionally advanced squamous cell cancer of the head and neck conducted at the University of Chicago over 7 years. Using Cox regression that adjusted for standard patient-level disease and demographic factors and neighborhood-level economic factors, we found a positive association between the distance patients traveled from their residence to the treatment center and survival. Patients who lived more than 15 miles from the treating institution had only one-third the hazard of death of those living closer (hazard ratio [HR] = 0.32, 95% confidence interval [CI] = 0.12 to 0.84). Moreover, with every 10 miles that a patient traveled for care, the hazard of death decreased by 3.2% (HR = 0.97, 95% CI = 0.94 to 0.99). Similar results were obtained for progression-free survival. Results of phase II curative-intent clinical trials in oncology that are conducted at specialized cancer centers may be confounded by patient travel distance, which captures prognostic significance beyond cancer stage, performance status, and wealth. More work is needed to determine what unmeasured factors travel distance is mediating.

  ABSTRACT: 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. 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. 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. 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.

  ABSTRACT: 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. Sixty-nine patients received six weekly doses of carboplatin (AUC2) and paclitaxel (135 mg/m2) followed by five cycles of TFHX. 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. 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.

  ABSTRACT: 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.

  ABSTRACT: 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.
