This will be relatively short and sweet after
my long posts on pancreatic cancer and breast cancer screening in people with
Peutz-Jeghers syndrome (PJS).
Both males and females with PJS are at
increased risk of cancer in a wide range of organs. Additionally, we're at risk
of both benign and malignant tumors of the reproductive tract.
A type of benign tumor called "sex cord
tumors" often affect young children, so that young girls may develop signs
of puberty as early as 2 years old. And young boys may develop precocious
puberty, gynecomastia (breasts), feminizing features and early growth.
In the past, these were surgically treated by
removing ovaries, breasts and testicles. Now they're usually treated through
hormonal manipulation.
But the problems change with age and females
are at increased risk for both benign and malignant ovarian tumors and a rare
cervical cancer. Males seem to be at increased risk of prostate and testicular
cancer - though the numbers are too low to bear this out.
The benign tumors can lead to hormonal
imbalance and I heard from a PJS researcher that some women with PJS have been
diagnosed because of menstrual problems, not polyp problems. Additionally,
fertility can be difficult for both women and men.
The rare cervical cancer originates deep
inside the cervix, not along its outer walls, and can't be detected by PAP
smears. It can present as a fluid discharge and sometimes pain or cramping.
Some experts suggest pelvic ultrasound exams of the cervix and ovaries, but not
all.
Note: Those with PJS (male and female) and reproductive tract abnormalities should have their tumors and pathology reports reviewed by Dr. Robert Young at MGH in Boston. He's a pathologist interested in PJS and our reproductive tract tumors.

He's truly seen it all and is an expert at sorting out the
rare and the common...may even contribute to treatment decision conversations:
Here are a variety of screening guidelines:
FOR FEMALES WITH PJS
St. Mark's in London
::: Cervical smear tests as per the national
screening programme (PAP smears age 25-49 every 3 years. Ages 50- 64, every 5
years).

The European experts:
Question: Should surveillance for genital
tract malignancies be performed in PJS?
The increase in ovarian tumour risk is mainly
not for epithelial ovarian cancer but for SCTAT, which can occur in very young
children (2 and 4 years of age reported in the study by Lim et al) although the
main risk appears to be in the fourth and fifth decades of life. Giardiello et
al reported a 21% lifetime risk of ovarian tumours, a risk of cervical cancer
of 9% by 64 years (mean age at diagnosis 34 years) and 10% of uterine cancer.
The risks observed by Hearle and colleagues are lower. They observed nine
gynaecological cancers (two uterine, two ovarian and five cervical), with a
risk of 1% at age 30 years, rising to 18% at age 60 years.
Conclusion: There is no evidence to support
routine screening for genital tract malignancies in PJS. However, expert
opinion advocates regular screening consisting of 2-3 yearly cervical smears
using liquid- based cytology (LBC) from age 25 years, testicular examination
and testicular ultrasound in patients where an abnormality is detected at examination.
Routine surveillance for endometrial and ovarian cancers is not recommended.
(Evidence level: IV, Grade of recommendation: C)

Guidelines from Dutch experts:
Pelvic exam, cervical smear, transvaginal
ultrasonography and CA-125 – annually starting age 25-30.
XXX
From eMedicine in the USA
Genitourinary in women - Annual pelvic
examination, pelvic ultrasound, and cervical smears; some reviews recommend
serum CA 125, endometrial biopsy annually from age 20 years onwards
FOR MALES WITH PJS
Testicular cancer surveillance is recommended
on the basis of expert opinion only. In a literature review all cancers
detected were Sertoli cell tumours and occurred at an average age of 9 years.
Annual testicular examination is recommended with ultrasound scanning reserved
for patients where an abnormality is found or precocious puberty develops.

From eMedicine in the USA:
Genitourinary in men - Annual testicular
examination; ultrasound if symptomatic from birth

Conclusion:
Conclusion:
Clearly, there is a lack of consensus
internationally. I hope that the experts will continue to collect and analyze
data (there are too few of us to achieve statistical significance) and to craft
screening guidelines based on the best available science and medical wisdom.
