Human papillomavirus in adolescents: lessons learned from decades of evaluation

Pediatric, adolescent, and young adult breast and reproductive tumors

Tumors of the breast and reproductive organs that occur in children, adolescents, and young adults (AYA) have different biological features and can present special challenges. Although prognosis for these tumors is generally favorable, the long-term effects of treatment can be debilitating. Treatments are often multimodal and may include surgery as well as chemotherapy and/or radiation, which can cause considerable distress and anxiety related to loss of femininity or masculinity, concern over future fertility, or sexual dysfunction. Thus, tumors of the reproductive organs in pediatric/AYA patients require special consideration of the treatment effects beyond the intended oncologic outcome. Multidisciplinary teams should be involved in their care and address issues of fertility, sexual dysfunction, and psychosexual concerns before treatment begins. This review addresses histology, risk factors, prognosis, staging and treatment of gynecologic, breast and testicular cancers in pediatric and AYA patients.

Recommendations and barriers to vaccination in systemic lupus erythematosus

Patients with Systemic Lupus Erythematosus (SLE) pose a unique dilemma pertaining to immunization against common pathogens. SLE patients are usually not immunized with vaccines based on the fear of either precipitating infection in this immunosuppressed patient population (with live vaccines) or aggravating autoimmunity and hence lupus flares (with any vaccines). However, elevated vulnerability to infection makes patients with SLE precisely the population that needs protection from vaccine-preventable diseases. A summary of guidelines from the Centers for Disease Control and Prevention, professional societies, review articles and expert opinions regarding use of individual vaccines applicable to adults with SLE is presented in this review.

Findings and Outcomes in a Prevaccination Cohort of Women Younger Than 25 Years Attending a Tertiary Colposcopy Service

OBJECTIVE

To describe clinical presentation and treatment in women younger than 25 years referred to the Royal Women's Hospital colposcopy clinic, before implementation of the National Human Papillomavirus Vaccination Program.

METHODS

Retrospective cohort analysis of women younger than 25 years referred to a tertiary hospital colposcopy clinic between 1998 and 2007. Clinical presentation and correlation between cervical cytology, biopsy, and histology at treatment was examined.

RESULTS

Approximately 14,635 colposcopies were undertaken in 4104 women (median age, 22 years); 3051 had abnormal referral cytology, of whom, 23.8% had high-grade disease on punch biopsy. High-grade disease was found in 15.1% of those with possible low-grade or low-grade cytology (293/1932), 42.4% of those with possible high-grade or high-grade cytology (474/1119). Sensitivity and specificity of colposcopy for high-grade disease (high-grade epithelial abnormality, adenocarcinoma in situ, cervical cancer up to 2 years follow-up) was 60.0% and 82.3%, respectively. Thirty-nine percent (n = 1180) with abnormal cytology had treatment, of which, 66.6% was ablative. Histological CIN3+ was found in 53.8% of those with a previous high-grade punch biopsy (126/234) at excisional treatment, and 23.0% of those with a previous low-grade punch biopsy (20/87) (relative risk, 2.3 [CI, 1.6-3.5]). Four cancers were detected (0.1% of the total cohort, 0.5% of those with a high-grade biopsy, and 1.7% of those with a high-grade biopsy who underwent excisional treatment.)

CONCLUSIONS

Before vaccination, young women experienced a high real-time burden of high-grade disease and high rates of intervention. These baseline data contribute to monitoring of HPV vaccination and revised cervical screening strategies.

HPV infection and vaccination in Systemic Lupus Erythematosus patients: what we really should know

Patients with Systemic Lupus Erythematosus (SLE) are at increased risk for infections. Vaccination is a powerful tool to prevent infections, even in immunocompromised patients. Most non-live vaccines are immunogenic and safe in patients with SLE, even if antibody titres are frequently lower than those of healthy controls. Human papillomavirus (HPV) infections are more prevalent in SLE patients when compared to the healthy population. Low-risk types of this virus cause anogenital warts, while high risk types are strongly related to pre-malignant cervical abnormalities and cervical cancer. HPV vaccines have been developed to prevent these conditions. Although little is known about HPV vaccination in SLE, few studies in patients with autoimmune rheumatic diseases (AIRDs) have shown that HPV vaccines are safe, and capable to induce an immunogenic response in this group of patients. To date, available data suggest that HPV vaccines can be given safely to SLE patients. Given the increased incidence of cervical abnormalities due to HPV in SLE patients, this vaccination should be encouraged.

Awareness of human papillomavirus and factors associated with intention to obtain HPV vaccination among Korean youth: quasi experimental study

BACKGROUND

This study aimed to determine the awareness among fifth-grade girls and boys of sexually transmitted diseases (STDs), cancer, and human papillomavirus (HPV), and to determine the factors associated with intention to obtain the HPV vaccination.

METHODS

A quasi experimental design was employed with Korean fifth-grade students as the subjects for this study (n=117). Prior to providing HPV education, the awareness and health beliefs regarding STDs and cancer prevention were assessed according to gender. After 2 hours of HPV education, gender comparisons were made with respect to the awareness and health beliefs, HPV knowledge, and intention to obtain the HPV vaccination, and the factors associated with that intention.

RESULTS

Prior to the 2hours education session, only two boys knew that HPV is a virus. There were significant gender differences with respect to responses to the statements "STD is preventable" (χ(2)=8.76, p=0.013) and "cancer is preventable" (χ(2)=6.37, p=0.041), and concerns about the pain associated with vaccine injection (z=-2.44, p=0.015). After HPV education, there were no significant gender differences in HPV knowledge and intention to obtain the HPV vaccination. Awareness that "HPV vaccine can prevent cervical cancer" was significantly related to intention to obtain the HPV vaccine among both boys and girls.

CONCLUSIONS

Increased HPV knowledge could positively influence the intention to obtain the HPV vaccination among youth. Thus, HPV education at elementary school would be helpful to make students aware of HPV and the importance of HPV prevention.
