Unsolicited patient complaints among radiation, medical, and surgical oncologists.

BACKGROUND: Unsolicited patient complaints (UPCs) about physician practices are nonrandomly associated with malpractice claims and clinical quality. The authors evaluated the distributions and types of UPCs associated with oncologists by specialty and assessed oncologist characteristics associated with UPCs. METHODS: This retrospective study reviewed UPCs associated with US radiation oncologists (ROs), medical oncologists (MOs), and surgical oncologists (SOs) from 35 health care systems from 2015 to 2018. Average total UPCs were compared by specialty in addition to sex, medical school graduation year, degree, medical school location, residency location, practice setting, and practice region. For continuous variables, linear regression was used to test for an association with total complaints. RESULTS: The study included 1576 physicians: 318 ROs, 1020 MOs, and 238 SOs. The average number of UPCs per physician was different and depended on the oncologic specialty: ROs had significantly fewer complaints (1.28; 95% confidence interval [CI], 1.02-1.54) than MOs (3.81; 95% CI, 3.52-4.10) and SOs (6.89; 95% CI, 5.99-7.79; P < .0001). In a multivariable analysis, oncologic specialty, recency of graduation, and academic practice were predictive of higher total UPCs (P < .05). UPCs described concerns with care and treatment (42.8%), communication (26.4%), accessibility (17.5%), concern for patient (10.3%), and billing (2.9%). CONCLUSIONS: ROs had significantly fewer complaints than MOs and SOs and may have a lower risk of malpractice claims as a group. In addition to oncologic specialty, a more recent year of medical school graduation and working at an academic center were independent risk factors for UPCs. Further research is needed to clarify the reasons underlying these associations and to identify interventions that decrease UPCs and associated risks. LAY SUMMARY: This study of 1576 oncologists found that radiation oncologists had significantly fewer complaints than medical oncologists, who in turn had significantly fewer complaints than surgical oncologists. Other characteristics associated with more patient complaints included recency of medical school graduation and practice in an academic setting. Oncologists' patient complaints provide information that may have practical applications for patient safety and risk management. Understanding and addressing the characteristics that increase the risk for complaints could improve patients' experiences and outcomes.

A Case Report of Malignant Eccrine Porocarcinoma Involving the Palm Requiring Surgical Excision and Free Flap Reconstruction.

BACKGROUND Eccrine porocarcinoma (EPC) was first described in 1963 as an epidermotropic eccrine carcinoma. Fifty years later, its etiology remains poorly understood. The infrequent nature of this disease merits further inquiry into its etiology, presentation, and standards of management. Furthermore, the propensity for metastasis, which may be as high as 31% on presentation, increases the importance of investigating this rare disease. CASE REPORT The patient was a 63-year-old mechanic who presented with the lesion as a chronic wound following a chemical exposure. The lesion involved the ulnar aspect of his right palm and had concern for extension to the underlying tendons. He underwent a wide excision extending from the wrist to the proximal interphalangeal joint, preserving the ulnar neurovascular bundle. The hand was reconstructed with an anterolateral thigh fascia perforator flap and a skin graft. He had an excellent functional and cosmetic recovery. Unfortunately, he developed metastases to the lymph nodes, necessitating an axillary lymphadenectomy followed by adjuvant chemoradiation using concurrent cisplatin and docetaxel with radiation for 6 weeks. Follow-up at 18 months found no recurrence. CONCLUSIONS Cases of EPC presenting in the fingers have been managed with amputation of the involved phalanges; however, in addition to obtaining complete excision with negative margins, surgeons who deal with tumors of the hand must also consider the goals of limb preservation, functional preservation, and functional reconstruction. Options for reconstruction following excision include primary closure, dermal regeneration templates, skin grafts, flaps, and free-tissue transfer, depending on what tissue types are needed.

A Recurrence of Bilateral Diffuse Sclerosing Lobular Hyperplasia of Breast: A Case Report.

Mammary sclerosing lobular hyperplasia is an uncommon benign fibroproliferative lesion of adolescent and young women, often of African American heritage with an incidence of ~3%. Patients generally complain of a palpable, painless, or slightly tender and well-defined lump in breast. Very rarely, this lesion may be bilateral and diffuse. The definitive diagnosis of sclerosing lobular hyperplasia requires histopathologic evaluation. Here, we describe a case of diffuse sclerosing lobular hyperplasia in a 29-year-old African American woman that required bilateral mastectomy and recurred bilaterally requiring second resections. This appears to be the first report of this phenomenon.

Selenium levels in human breast carcinoma tissue are associated with a common polymorphism in the gene for SELENOP (Selenoprotein P).

Selenium supplementation of the diets of rodents has consistently been shown to suppress mammary carcinogenesis and some, albeit not all, human epidemiological studies have indicated an inverse association between selenium and breast cancer risk. In order to better understand the role selenium plays in breast cancer, 30 samples of tumor tissue were obtained from women with breast cancer and analyzed for selenium concentration, the levels of several selenium-containing proteins and the levels of the MnSOD anti-oxidant protein. Polymorphisms within the genes for these same proteins were determined from DNA isolated from the tissue samples. There was a wide range of selenium in these tissues, ranging from 24 to 854ng/gm. The selenium levels in the tissues were correlated to the genotype of the SELENOP selenium carrier protein, but not to other proteins whose levels have been reported to be responsive to selenium availability, including GPX1, SELENOF and SBP1. There was an association between a polymorphism in the gene for MnSOD and the levels of the encoded protein. These studies were the first to examine the relationship between selenium levels, genotypes and protein levels in human tissues. Furthermore, the obtained data provide evidence for the need to obtain data about the effects of selenium in breast cancer by examining samples from that particular tissue type.

A hyperpigmented perianal nodule.

Basal cell carcinoma (BCC) is the most common cutaneous malignancy. Ultraviolet light is an important risk factor for the pathogenesis of BCCs; the vast majority are found in sun-exposed areas. BCCs occurring in the perianal or genital regions are seldom seen. Less than 1% of all BCCs occur at these sites. Etiologic factors other than solar exposure must be taken into account for such cases. We report a rare case of BCC that was initially detected during a routine colonoscopy.

Cutaneous squamous cell carcinoma responding serially to single-agent cetuximab.

Cetuximab (Erbitux) is a recombinant, chimeric monoclonal antibody that binds with high affinity to the extracellular ligand-binding domain of human epidermal growth factor receptor. We report a case of repeated responses to cetuximab in a patient with nonresectable squamous cell skin cancer having strong human epidermal growth factor receptor expression. Nonmelanoma skin cancer is the most common cancer in the US, with more than 1 million new cases detected annually, of which 20-25% are squamous cell carcinomas. Although most primary cutaneous squamous cell carcinomas have a high clinical cure rate and are easily treated, the small subset of cancers that recur or metastasize has a poor prognosis, and accounts for approximately 2000 deaths per year. Treatment with cetuximab should be considered for human epidermal growth factor receptor expressing tumors in a palliative setting.

Osteosarcoma invading adrenal gland: rare cause of adrenal mass.

Adrenal gland metastasis from osteogenic sarcoma is extremely rare and is an atypical location for metastasis. Vascular hepatic exclusion techniques and the use of venovenous bypass with cardiac surgical techniques may be required to resect large adrenal masses that have invaded the inferior vena cava to achieve curative resection. The use of newer chemotherapeutic agents and aggressive surgical resection have prolonged the survival of patients with osteosarcoma.

A Phase I trial of TNFerade biologic in patients with soft tissue sarcoma in the extremities.

PURPOSE: TNFerade is a second-generation replication-deficient adenovector carrying a transgene encoding human tumor necrosis factor alpha under control of a radiation- induced promoter. The objective of this study was to assess the tolerance of combining TNFerade and radiation therapy in patients with soft tissue sarcomas of the extremity. EXPERIMENTAL DESIGN: TNFerade was administered in combination with single-daily fractionated radiation therapy in 14 patients with soft tissue sarcoma of the extremities. Three escalating dose levels of TNFerade (4 x 10(9) -4 x 10(11) particle units) were planned, given in 1 log increments by intratumoral injections, twice weekly during week 1 and once weekly during weeks 2-5 of radiation therapy. RESULTS: TNFerade was well tolerated with no dose-limiting toxicities noted. Grade 1-2 chills (50.0%), fever (43.0%), fatigue (36.0%), and flu-like symptoms (21.0%) were the most common side effects. Serum-tumor necrosis factor alpha levels were low in all of the patients (<15 pg/mL). No patients had virus-detected blood, sputum, or urine cultures. Of the 13 evaluable patients, 11 received TNFerade preoperatively, and 2 received the treatment for palliation. Eleven patients (85%) showed objective or pathological tumor responses (2 complete and 9 partial), and 1 had stable disease. Partial responses were achieved despite some of these tumors being very large (up to 675 cm(2)). Of the 11 patients who underwent surgery, 10 (91%) showed a pathological complete response/partial response. CONCLUSION: TNFerade + radiation therapy was well tolerated in the treatment of patients with soft-tissue sarcoma of the extremity. The high number of objective responses observed warrants additional studies of this approach in a larger controlled prospective trial.

Clinical node-negative thick melanoma.

BACKGROUND: Patients with T4 N0 M0 melanoma are considered at high risk for having occult metastases, and adjuvant therapy is usually recommended. HYPOTHESIS: Long-term survival in patients with thick melanoma is not universally poor. DESIGN: A retrospective study. SETTING: University teaching hospital. PATIENTS: We evaluated clinical node-negative thick (> or = l4.0 mm) melanoma in 151 patients who received their primary definitive surgical treatment in our department. None of these patients received any adjuvant therapy. RESULTS: Median follow-up was 44 months; median thickness, 5.5 mm. Median overall (OS) and disease-free survivals (DFS) were 70 (5-year survival, 52%) and 51 months (5-year survival, 47%), respectively. Patients with node-positive disease faired significantly worse than did those with node-negative disease. Median OS and DFS for patients with node-positive disease were 49 and 32 months (5-year survival, 35%), respectively, compared with 209 (5-year survival, 61%) and 165 months (5-year survival, 56%), respectively, for patients with node-negative disease. Similarly, OS and DFS were significantly lower when the primary tumor had at least 5 mitoses/mm(2) or was located in the head and neck region. After multivariate analysis, status of the lymph nodes was the most predictive variable for OS and DFS. CONCLUSIONS: The thickness of melanoma, by itself, should not be used as a criterion for adjuvant therapy. Other prognostic factors should be considered.
