paywalled: Early Postoperative CT as a Prognostic Biomarker in Patients With Advanced Ovarian, Tubal, and Primary Peritoneal Cancer Deemed Optimally Debulked at Primary Cytoreductive Surgery

Early Postoperative CT as a Prognostic Biomarker in Patients With Advanced Ovarian, Tubal, and Primary Peritoneal Cancer Deemed Optimally Debulked at Primary Cytoreductive Surgery

CONCLUSION:

Our study showed that residual disease larger than 1 cm was present on early postoperative CT in almost half of the patients deemed to have optimally debulked disease at primary cytoreduction.

CT diagnosis of intrasplenic metastasis from ovarian carcinoma

 We concluded that CT can demonstrate intraparenchymal and infiltrative splenic metastasis in patients with ovarian cancer even in the absence of increased CA 125 levels.

Study Downplays Risk of CT Scans - MedicineNet

"More often than not, patients should be getting that CT scan because the risk of the underlying cause is higher than from radiation."

"...The findings were similar -- with deaths ranging from 2 percent to 33 percent -- in the more than 15,000 who got abdominal CTs. The researchers think 23 people in the entire group would have gotten cancer due to radiation exposure."

""In the patients getting 15 or more scans, all of them had pretty significant disease, where their expected mortality was likely to occur much sooner than the chances of the radiation-induced cancer taking effect," Zondervan said. In other words: Those who were the sickest, requiring the most CT scans, would probably die before any cancer caused by the CT radiation could start hurting them."

U.S. Medicare - Study calls CMS' CT scan measure inaccurate - Healthcare business news and research | Modern Healthcare

A study in the Annals of Emergency Medicine concludes that a new imaging efficiency measure from the CMS known as OP-15 is not accurate in determining which hospitals perform CT scans under appropriate circumstances.

Follow-Up Study of the Correlation Between Postoperative Computed Tomographic Scan and Primary Surgeon Assessment in Patients With Advanced Ovarian, Tubal, or Peritoneal Carcinoma Reported to Have Undergone Primary Surgical Cytoreduction to Residual Disease of 1 cm or Smaller

Conclusions: On this follow-up analysis, only age, stage, and residual disease were significant prognostic factors for overall survival. Discordant findings between the primary surgeon's assessment and the postoperative CT scan findings of residual disease was not an independent prognostic factor.

"Does this mean you should avoid CT scans? No, don't swing from scan-a-mania to scan-a-phobia. These tests can be lifesavers, provided you and your doctor use them only when the benefits outweigh the risks....."

Use of CT Scans Linked to Cancer Risk, Studies Say | netReturns | e-Newsletter

"There is considerable disagreement in the scientific community about the validity of these models," notes Rosaleen Parsons, M.D., chair of the department of diagnostic imaging at Fox Chase Cancer Center. "And some scientists believe the radiation dose from these CT scans may not lead to any increased risk of cancer."

In the second study, conducted at the University of California-San Francisco, researchers compared CT scan use at four San Francisco Bay area facilities. They found that the amount of radiation from a CT scan may be up to four times greater than estimated in previous studies. In addition, they noted significant differences among different institutions and, in some instances, within the same institution, when looking at the radiation dose associated with CT scans.
