RESUMO

Purpose/Objectives: Screening for distress is a key priority in cancer care, and African American patients may experience increased distress compared to White patients. However, this question has not yet been addressed in Louisiana. The purpose of the present study was to examine the relationship between African American race and distress at a cancer center in Louisiana.Design/Methods: This was a retrospective study of 1,544 patients who were treated at an academic cancer center in 2015. Extracted data included patient self-reports of distress using the single-item Distress Thermometer (DT) and demographic and clinical characteristics. Hypotheses were tested using logistic regression.Findings: Distress was present in 19.7% of the sample. In univariate analyses, African American patients were more likely than White patients to experience distress (OR = 1.38, p = .013). However, race was no longer associated with distress in a multivariate analysis that adjusted for the covariates of age, gender, cancer site, presence of metastases, and number of distress screenings (OR = 1.07, p = .670). Distress was more common in patients who were younger (OR = 2.26, p < .001), diagnosed with lung/bronchus cancer (OR = 5.28, p < .001), or screened more often (OR = 5.20, p < .001). Distress was less common among patients with female breast cancer (OR = 0.39, p = .015).Conclusions/Implications: This study suggests that African American individuals with cancer in Louisiana are at increased risk for distress, but that this can be attributed to African American patients being younger, more likely to have lung cancer, and screened more frequently. Implications include careful consideration of patient race, age, and cancer site during distress management in cancer care.

RESUMO

Objective: Social support is fundamentally important to the well-being of patients with cancer, and informal caregivers often wish they had better insight into how to help. The aims of this study were to quantify the types of social support that patients qualitatively expressed as important, and examine whether demographics and mental health symptoms explained the type of support desired. Methods: A sample of 82 patients with cancer (Gender: 65.9% Male, Age: M = 57.5, Race/Ethnicity: 90.2% White, non-Latino/a) completed measures of demographics, health, anxiety, and depression, and responded to an open-ended question asking them to list three types of support that they desire from their caregivers. These responses were then reliably coded into 18 different categories. Results: Most commonly, participants expressed a desire for companionship (45%). Other common requests included empathy (33%), home care support (28%), information support (16%), being treated the same (15%), and help with appointments (13%). Patients who were more anxious were more likely to desire companionship (OR = 4.41, p = .033), and younger patients were more likely to desire home care support (OR = 7.24, p = .016). Conclusion: Findings have implications for providing individually-tailored social support to patients with cancer.

RESUMO

OBJECTIVES: Changes in cognitive function have been identified in and reported by many cancer survivors. These changes have the potential to impact patient quality of life and functional ability. This prospective longitudinal study was designed to quantify the incidence of change in cognitive function in newly diagnosed ovarian cancer patients throughout and following primary chemotherapy. METHODS: Eligible patients had newly diagnosed, untreated ovarian cancer and had planned to receive chemotherapy. Web-based and patient reported cognitive assessments and quality of life questionnaires were conducted prior to chemotherapy, prior to cycle four, after cycle six, and six months after completion of primary therapy. RESULTS: Two-hundred-thirty-one evaluable patients entered this study between May 2010 and October 2011. At the cycle 4 time point, 25.2% (55/218) of patients exhibited cognitive impairment in at least one domain. At the post-cycle 6 and 6-month follow up time points, 21.1% (44/208) and 17.8% (30/169) of patients, respectively, demonstrated impairment in at least one domain of cognitive function. There were statistically significant, but clinically small, improvements in processing speed (p<0.001) and attention (p<0.001) but not in motor response time (p=0.066), from baseline through the six-month follow up time period. CONCLUSIONS: This was a large, prospective study designed to measure cognitive function in ovarian cancer. A subset of patients had evidence of cognitive decline from baseline during chemotherapy treatment in this study as measured by the web-based assessment; however, changes were generally limited to no more than one domain.

RESUMO

While robotic surgery has seen much success in the treatment of gynecologic malignancies, the technical aspects of this approach raise concern for spreading tumor cells within the peritoneal cavity and to trocar sites. To date, robotic trocar site metastases have been identified following surgery for both endometrial and cervical cancer.

RESUMO

We have investigated the magnitude of circadian variation in Isokinetic and Isometric strength of the knee extensors and flexors, as well as back squat and bench press performance using the MuscleLab force velocity transducer. Ten resistance-trained males (mean±SD: age 21.5 ± 1.1 years; body mass 78.3 ± 5.2 kg; height 1.71 ± 0.07 m) underwent a) three to four familiarization sessions on each dynamometer and b) four sessions at different times of day (03:00, 09:00, 15:00 and 21:00 h). Each session was administered in a counterbalanced order and included a period when Perceived onset of mood states (POMS), then rectal and muscle temperature (Trec, Tm) was measured at rest, after which a 5-min standardized 150 W warm-up was performed on a cycle ergometer. Once completed, Isokinetic (60 and 240°·s-1 for extension and flexion) and Isometric dynamometry with peak torque (PT), time-to-peak-torque (tPT) and peak force (PF) and % activation was measured. Lastly, Trec and Tm were measured before the bench press (at 30, 50 and 70 kg) and back squat (at 40, 60 and 80 kg) exercises. A linear encoder was attached to an Olympic bar used for the exercises and average force (AF), peak velocity (PV) and time-to-peak-velocity (tPV) were measured (MuscleLab software; MuscleLab Technology, Langesund, Norway) during the concentric phase of the movements. Five-min recovery was allowed between each set with three repetitions being completed. General linear models with repeated measures and cosinor analysis were used to analyse the data. Values for Trec and Tm at rest were higher in the evening compared to morning values (Acrophase Φ: 16:35 and 17:03 h, Amplitude A: 0.30 and 0.23°C, Mesor M: 36.64 and 37.43°C, p < 0.05). Vigor, happy and fatigue mood states responses showed Φ 16:11 and 16:03 h and 02:05 h respectively. Circadian rhythms were apparent for all variables irrespective of equipment used where AF, PF and PT values peaked between 16:18 and 18:34 h; PV, tPV and tPT peaked between 05:54 and 08:03 h (p < 0.05). In summary, circadian rhythms in force output (force, torque, power, and velocity) were shown for isokinetic, isometric dynamometers and complex multi-joint movements (using a linear encoder); where tPV and tPT occur in the morning compared to the evening. Circadian rhythms in strength can be detected using a portable, low-cost instrument that shows similar cosinor characteristics as established dynamometers. Hence, muscle-strength can be measured in a manner that is more directly transferable to the world of athletic and sports performance.

RESUMO

PURPOSE: The efficacy of immune checkpoint blockade in gestational trophoblastic neoplasia (GTN) remains uncertain. We report the results of the GTN cohort of SWOG S1609 dual anti-CTLA-4 and anti-PD-1 blockade in rare tumors (DART). PATIENTS AND METHODS: This prospective, open-label phase II trial evaluated ipilimumab plus nivolumab across multiple rare tumor cohorts, including GTN. Eligible patients received nivolumab 240 mg, i.v. every 2 weeks and ipilimumab 1 mg/kg i.v. every 6 weeks. The primary endpoint was overall response rate [ORR; complete response (CR) + partial response (PR)] by quantitative serum beta human chorionic gonadotropin (ß-hCG); secondary endpoints included progression-free survival (PFS), overall survival (OS), and toxicity. RESULTS: Four patients with refractory GTN enrolled and received therapy. At 11 months of ongoing follow-up, 3 of 4 patients responded [ORR = 75% (CR, 25%, n = 1, tumor mutation burden = 1 mutation/megabase; PD-L1 tumor proportion score = 50%); PR, 50%, n = 2)]. Responders included malignant gestational trophoblastic neoplasm (n = 1, CR, PFS 11+ months) and choriocarcinoma (n = 2, both PRs, PFS 10+ and 6+ months). One patient with epithelioid trophoblastic tumor experienced disease progression. The 6-month PFS was 75% [95% confidence interval (CI), 43%-100%], and the median PFS was not reached (range, 35-339+ days); all 4 patients were alive at last follow-up. Two patients experienced grade 3 immune-related toxicity (arthralgia and colitis); there were no grade ≥4 events. CONCLUSIONS: Ipilimumab plus nivolumab demonstrated efficacy in chemotherapy-refractory GTN, an ultra-rare cancer affecting young women. Three of 4 patients achieved ongoing objective responses with a reasonable safety profile at 6-11+ months.

RESUMO

OBJECTIVES: To identify patterns of metastasis in patients with recurrent ovarian cancer. The influence of the route of chemotherapy administration and sequence of agents on those patterns is also examined. METHODS: A total of 233 women were treated for primary and secondary recurrences after a diagnosis of stage III ovarian cancer. As initial treatment, all underwent optimal debulking surgery followed by combined intraperitoneal/intravenous (IP) chemotherapy with cisplatin/paclitaxel (99 of the 233 women) or intravenous (IV) carboplatin/paclitaxel (134 of the 233 women). Recurrent disease was then treated with either carboplatin with or without liposomal doxorubicin (CLD) or bevacizumab (BEV). The data were reviewed and the types of treatment, sites of metastasis, and timing of recurrence are described. RESULTS: Thirty-five subjects developed extraperitoneal recurrent ovarian cancer, with 26 subjects (74%) after IP treatment, and 9 subjects (26%) after IV treatment. Of these extraperitoneal recurrences, 26 were in the thoracic/pulmonary cavity, 7 were within the central nervous system (CNS), and 2 were in the cutaneous tissues. The CNS and cutaneous lesions were secondary recurrences, and all occurred in subjects who had initially received IP cisplatin/paclitaxel followed by IV BEV for recurrent disease. CONCLUSIONS: Extraperitoneal recurrences were more common in women treated with IP chemotherapy for ovarian cancer. Specifically, women treated with IV BEV as secondary therapy after IP were at particularly high risk of extraperitoneal metastases, including in the CNS and cutaneous tissues. Physicians should be aware of the possibility of unusual metastases after the combination of IP chemotherapy and BEV, and future prospective studies of this population should carefully evaluate recurrence site patterns.

RESUMO

HYPOTHESIS: The use of intraperitoneal (IP) chemotherapy as treatment for ovarian cancer has been demonstrated to result in improved survival. However, it is associated with significant toxicity, resulting in the early discontinuation of therapy in many cases. This report quantifies and analyzes the reasons why patients discontinue therapy before completion and discusses strategies for improvement. METHODS: One hundred seventy-seven women with ovarian cancer who received IP chemotherapy for a 10-year period at a regional cancer center were followed, and demographic and treatment data were collected. SigmaStat (v2.0) was used to make statistical calculations regarding the data. RESULTS: One hundred seventy-seven subjects received 915 cycles of IP therapy. One hundred forty subjects received IP chemotherapy as initial treatment. Ninety-five (68%) of the 140 subjects completed 6 planned cycles. Thirty-seven subjects received IP for recurrent disease. Only 14 (38%) of the 37 subjects completed 6 cycles (P = 0.001). The most common reason for noncompletion of IP therapy was port occlusion (39/68 of the patients, 57%). Very few subjects refused treatment (9/68 of the patients, 13%). The rate of completion of therapy improved over time in this program (2001, 36%; 2009, 75%). CONCLUSIONS: The rate of completion of IP chemotherapy was higher in this institution than in other reports, including randomized multicenter trials. Port occlusion was the most common reason why IP chemotherapy was not completed. Subjective reasons for stopping therapy were rare. The establishment of a comprehensive, coordinated IP administration program is likely to result in improved completion rates. Completion rates within an institution improve with experience as well.

RESUMO

The aim of this retrospective study was to evaluate differences in treatment of embryonal rhabdomyosarcoma (RMS) of the uterus in 2 premenopausal women. We discuss adjuvant chemotherapy and use of ChemoFx Assay (Precision Therapeutics, Pittsburgh, PA) to guide choice of active chemotherapeutic agents. Two premenopausal patients were identified with a pathologic diagnosis of embryonal RMS of the uterus. Both met inclusion criteria for the study. A 21-year-old woman underwent a staging abdominal hysterectomy for a variant of embryonal RMS. Vincristine, actinomycin D, and cyclophosphamide were given adjunctively for a complete response. A 20-year-old woman underwent a diagnostic dilation and curettage revealing embryonal RMS. Initial treatment included an abdominal hysterectomy and nodal sampling. Presentation to a subsequent gynecologic oncologist 7 months later revealed recurrence. Carboplatin, doxorubicin, and paclitaxel provided a partial response. After a second surgical resection, ChemoFx Assay identified ifosfamide and mitomycin C as active agents and resulted in a complete response. Recommended treatment includes surgery and chemotherapy with possible radiation therapy if deemed necessary. The benefit of adding neoadjuvant or adjuvant chemotherapy and radiation therapy allows for a conservative surgical approach and improved survival. Choosing active chemotherapy agents can be aided by ChemoFx Assay. The chemotherapy most commonly used for treatment of embryonal RMS is a combination of vincristine, actinomycin D, and cyclophosphamide.

RESUMO

PURPOSE: In vitro testing of the activity of chemotherapeutic agents has been suggested as 1 method to optimally select drugs for patients with ovarian cancer. There are limited prospectively obtained data examining the clinical utility of this approach. We sought to obtain a preliminary assessment of this strategy in a trial that examined the administration of neoadjuvant chemotherapy followed by surgical cytoreduction and intraperitoneal chemotherapy in women with advanced ovarian cancer. METHODS: Women with stage III/IV epithelial ovarian carcinoma that presented with large-volume disease were treated with neoadjuvant intravenous paclitaxel and carboplatin for three 21-day cycles followed by cytoreductive surgery. If optimally debulked, patients received intravenous paclitaxel, intraperitoneal carboplatin and intraperitoneal paclitaxel for six 28-day cycles. Tumor cloning assay results (Oncotech) were correlated with progression-free survival. RESULTS: Sixty-two patients (58 eligible) were registered from March 2001 to February 2006. Thirty-six eligible patients had interval debulking and 26 received postcytoreduction chemotherapy. Twenty-two patients had tumor cloning assay results available. The clinical features of this population were similar to those of the larger group of women who entered this study. There was no difference in progression-free survival between patients whose cancers were defined as 'resistant' or 'nonresistant' to either platinum or paclitaxel. CONCLUSIONS: While the small patient numbers in this trial do not permit definitive conclusions, these data fail to provide support for the argument that prospectively obtained in vitro data regarding platinum or paclitaxel resistance will be highly predictive of clinical outcome in advanced ovarian cancer.

RESUMO

OBJECTIVE: Intraperitoneal (IP) chemotherapy prolongs survival in optimally reduced ovarian cancer patients. For patients in whom optimal debulking cannot be achieved, one could incorporate IP therapy post-operatively if the cancer was optimally debulked following neoadjuvant chemotherapy. We sought to evaluate overall survival (OS), progression-free survival (PFS), percent of patients optimally debulked and toxicity in patients treated with this strategy. METHODS: Women with adenocarcinoma by biopsy or cytology with stage III/IV (pleural effusions only) epithelial ovarian, fallopian tube or primary peritoneal carcinoma that presented with bulky disease were treated with neoadjuvant intravenous (IV) paclitaxel 175 mg/m2 and carboplatin AUC 6 q 21 daysx3 cycles followed by surgery (if >/=50% decrease in CA125). If optimally debulked they received IV paclitaxel 175 mg/m2 and IP carboplatin AUC 5 (day 1) and IP paclitaxel 60 mg/m2 (day 8) q 28 daysx6 cycles. RESULTS: Sixty-two patients were registered. Four were ineligible. Fifty-six were evaluated for neoadjuvant chemotherapy toxicities. One patient died of pneumonia. Five patients had grade 4 toxicity, including neutropenia (3), anemia, leukopenia, anorexia, fatigue, muscle weakness, respiratory infection, and cardiac ischemia. Thirty-six patients had debulking surgery. Two had grade 4 hemorrhage. Twenty-six patients received post-cytoreduction chemotherapy. Four had grade 4 neutropenia. At a median follow-up of 21 months, median PFS is 21 months and median OS is 32 months for all 58 patients. PFS and OS for the 26 patients who received IV/IP chemotherapy is 29 and 34 months respectively. CONCLUSIONS: These results compare favorably with other studies of sub-optimally debulked patients.

RESUMO

OBJECTIVE: While primary cisplatin-based intraperitoneal chemotherapy has been shown to favorably impact survival in small-volume residual advanced ovarian cancer, there is a need to develop strategies that improve the effectiveness of this approach. METHODS: A multi-center phase 2 trial was conducted that added intravenous pegylated liposomal doxorubicin (day 8; 30-40 mg/m(2)) to a regimen of intraperitoneal cisplatin (day 2; 75 mg/m(2)) and intravenous (day 1; 135 mg/m(2)) plus intraperitoneal (day 8; 60 mg/m(2)) paclitaxel. Treatment was initially delivered on an every 3-week schedule, but was modified to an every 4-week program due to excessive toxicity. Patients were to receive 6 cycles of this regimen. RESULTS: Of 68 patients entering this trial, 63 patients were eligible and evaluable, of whom 39 (62%) completed 6 cycles. Overall, 32 (51%) experienced at least 1 grade 4 or worse toxicity (most commonly hematologic) including 5 treatment-related deaths. Median progression-free survival (PFS) was 25 months (2-year PFS: 52%) and median overall survival 51 months, an outcome similar to previous reports of cisplatin-based intraperitoneal chemotherapy in comparable patient populations. Seventeen patients (27% of all eligible patients) were without evidence of disease recurrence >4 years following entry into the trial. CONCLUSION: Both the overall trial outcome, and specifically the excessively severe systemic toxicity of this regimen would prevent its future development in this exact form. The provocative PFS in a subset of individuals should encourage the development of alternative strategies designed to optimize the delivery of regional therapy in ovarian cancer management.

RESUMO

OBJECTIVES: To determine the effect of participation in clinical trials on survival of women with ovarian cancer. Disease-specific factors and demographics were also examined. METHODS: A total of 158 women were treated for ovarian cancer at a regional cancer center. All patients were offered treatment with surgery/chemotherapy and were screened at diagnosis for participation in clinical research. Progression-free and overall survival, as well as demographic- and treatment-related data, were recorded. RESULTS: Fifty-three participated in clinical trials and 105 did not. On-study versus off-study subjects were similar in age (64.1 vs 63.5 years), ethnicity (87% vs 85% white), performance status (100% 0-1 Gynecologic Oncology Group scale), and urban versus rural lifestyle (58% vs 55% urban). Stage of disease, histologic subtype, and type/amount of therapy were also similar. Kaplan-Meier analysis showed superior overall survival for on-study subjects (median, 46 vs 25 months, 95% confidence interval, 1.0299-2.1505 months, P = 0.0343). A trend toward improved progression-free survival approached significance for on-study subjects (median, 23 vs 9 months, 95% confidence interval, 0.9545-2.0022 months, P = 0.0866). CONCLUSIONS: Women with ovarian cancer who participate in clinical trials at this institution have improved survival compared with those who are treated with standard therapies. No other factors examined were associated with treatment completion or survival. Further, participation in clinical research does not vary by age, ethnicity, urban versus rural lifestyle, or cancer stage or histologic subtype. However, disclosure of this information to potential clinical trial participants may represent an ethical conflict and should be carefully considered in light of existing ethical guidelines for human subject research.

RESUMO

We have investigated the magnitude of diurnal variation in back squat and bench press performance using the MuscleLab force velocity transducer. Thirty resistance-trained males (mean ± SD: age 21.7 ± 1.4 years; body mass 80.5 ± 4.5 kg; height 1.79 ± 0.06 m) underwent two sessions at different times of day: morning (M, 07:30 h) and evening (E, 17:30 h). Each session included a period when rectal temperature (Trec) was measured at rest, a 5-min standardized 150 W warm-up on a cycle ergometer, then defined programme of bench press (at 20, 40 and 60 kg) and back squat (at 30, 50 and 70 kg) exercises. A linear encoder was attached to an Olympic bar used for the exercises and average force (AF), peak velocity (PV) and time-to-peak velocity (tPV) were measured (MuscleLab software; MuscleLab Technology, Langesund, Norway) during the concentric phase of the movements. Values for Trec at rest were higher in the evening compared to morning values (0.48°C, P < 0.0005). Daily variations were apparent for both bench press and back squat performance for AF (1.9 and 2.5%), PV (8.3 and 12.7%) and tPV (-16.6 and -9.8%; where a negative number indicates a decrease in the variable from morning to evening). There was a main effect for load where AF and tPV increased and PV decreased from the lightest load to the heaviest for both bench press and back squat (47.1 and 80.2%; 31.7 and 57.7%; -42.1 and -73.9%; P < 0.0005 where a negative number indicates a decrease in the variable with increasing load). An interaction was found only for tPV, such that the tPV occurs earlier in the evening than the morning at the highest loads (60 and 70 kg) for both bench press and back squat, respectively (mean difference of 0.32 and 0.62 s). In summary, diurnal variation in back squat and bench press was shown; and the tPV in complex multi-joint movements occurs earlier during the concentric phase of exercise when back squat or bench press is performed in the evening compared to the morning. This difference can be detected using a low cost, portable and widely available commercial instrument and enables translation of past laboratory/tightly controlled experimental research in to main-stream coaching practice.

RESUMO

PURPOSE: We sought to test the hypothesis that the presence of telomerase activity in peritoneal washings of patients treated for ovarian carcinoma is a sensitive and specific indicator of the presence of residual disease. We hypothesized that this test, if added to second-look procedure protocols, could help determine whether residual disease is present or not in patients who have completed their adjuvant chemotherapy for ovarian carcinoma. EXPERIMENTAL DESIGN: Peritoneal washings were obtained from 100 consecutive patients undergoing a second-look procedure after treatment for ovarian carcinoma (cases) and from 100 patients undergoing surgery for benign gynecological conditions (controls). The washings were assayed for telomerase activity using the telomerase repeat amplification protocol. The results were compared to the histological and cytological findings. RESULTS: Among our 100 cases, 82 (82%) had either positive second-look procedures or expressed telomerase in their peritoneal washings. Fifty-three (53%) had positive second-look procedures, whereas 66 (66%) tested positive for telomerase. Twenty-nine of the 47 patients (62%) with negative second-look procedures tested positive for telomerase. Of the 53 patients with positive second-look procedures, 37 (70%) tested positive for telomerase. None of the 100 controls (0%) expressed telomerase in their peritoneal washings. CONCLUSIONS: Telomerase activity in peritoneal washings of patients treated for ovarian carcinoma and undergoing a second-look procedure may provide a means of increasing the sensitivity of such procedures for the detection of residual disease while maintaining a high level of specificity.

RESUMO

Rhabdomyosarcomas (RMSs) are malignant soft-tissue tumors arising from skeletal muscle progenitor cells. They are most commonly diagnosed in children and adolescents and are rare in adults. These tumors arise from a variety of anatomical sites, including the head and neck, urogenital tract, and extremities. Classification of RMSs depends on histopathologic and immunohistochemical features. Embryonal and alveolar subtypes are more common in children and adolescents, whereas the pleomorphic subtype is seen almost exclusively in adults. Adult RMS is associated with poor outcomes and high recurrence rate. Because of the low incidence of adult RMS, most published reports of RMS in adults are either case series or retrospective analyses, and most treatment protocols are extrapolated from clinical trials performed in children. The present report describes a 61-year-old woman with RMS whose presentation included atypical symptoms.

RESUMO

OBJECTIVE: To estimate the efficacy of isotretinoin for prevention of progression of low-grade squamous intraepithelial lesions (SIL) of the cervix to high-grade lesions or invasive cervical cancer; to estimate the regression rate of low-grade SIL with isotretinoin and the toxicity of isotretinoin in this setting; and to correlate serum CD4 levels with progression of low-grade SIL. METHODS: A randomized, phase III, observation-controlled, multicenter trial was performed in which 117 human immunodeficiency virus (HIV)-positive women with low-grade SIL of the cervix received either oral isotretinoin at 0.5 mg/kg per day for 6 months or observation. Papanicolaou smears and colposcopy/biopsy were done at regular intervals during follow-up. The primary endpoint was progression to high-grade SIL or cervical cancer. RESULTS: Twenty-one of 102 women (20.6%) completing follow-up experienced progression to high-grade SIL, 13 in the observation group and eight in the isotretinoin group. This difference was not significant (P =.29). No cases of invasive cancer were seen. Baseline CD4 levels were lower than anticipated (median 329 cells/mm(3)), but not associated with time to progression (P =.36). Most subjects (63 of 102, 61.7%) used highly active antiretroviral therapy. Subjects under age 30 were more likely to progress than those older than 30 (P =.046). CONCLUSION: Isotretinoin was not associated with longer time to progression of low-grade SIL. This appears to be a chronic condition in HIV-positive women, with a low risk of progression and significant rate of resolution. As in the general population, observation without excisional therapy may be appropriate for HIV-positive women with low-grade SIL.

RESUMO

Cervical neoplasia has been associated with human immunodeficiency virus (HIV) infection. Both preinvasive disease and invasive cervical cancer have been reported to have a much poorer outcome in HIV-infected women than in the general population. The use of highly active antiretroviral therapy (HAART) has resulted in significant improvements in the treatment of HIV infection, including a decrease in the incidence and severity of several acquired immune deficiency syndrome (AIDS)-related malignancies. Two cases of cervical dysplasia in HIV-infected women are presented, one from the pre-HAART era, who subsequently developed invasive cervical cancer and died, and one in whom HAART was used with good outcome. Data from several reports of the use of HAART in HIV-infected women indicates that the prognosis for cervical neoplasia is improved. Possible reasons for this improvement include better immune function seen in HAART-treated women, as well as increased surveillance for cervical neoplasia in HIV-infected women in recent years. However, the future impact of improved HIV care, including HAART, on cervical neoplasia is unclear.
