A woman being treated with docetaxel.
However, this approach, while standard in many places, especially the United States, is out of favor due to costs and the high level of expertise required to perform successful surgery. Sperm banking is frequently carried out prior to the procedure as with chemotherapy , as there is a risk that RPLND may damage the nerves involved in ejaculation, causing ejaculation to occur internally into the bladder rather than externally.
Many patients are instead choosing surveillance, where no further surgery is performed unless tests indicate that the cancer has returned.
This approach maintains a high cure rate because of the growing accuracy of surveillance techniques.
Adjuvant treatment[ edit ] Since testicular cancers can spread, patients are usually offered adjuvant treatment - in the form of chemotherapy or radiotherapy - to kill any cancerous cells that may exist outside of the affected testicle.
The type of adjuvant therapy depends largely on the histology of the tumor i. If the cancer is not particularly advanced, patients may be offered careful surveillance by periodic CT scans and blood tests, in place of adjuvant treatment.
Before , survival rates from testicular cancer were low.
Since the introduction of adjuvant chemotherapy , chiefly platinum-based drugs like cisplatin and carboplatin , the outlook has improved substantially. Although to new cases of testicular cancer occur in the United States yearly, only men are expected to die of the disease.
Radiation is ineffective against and is therefore never used as a primary therapy for nonseminoma. Non-seminoma[ edit ] Chemotherapy is the standard treatment for non-seminoma when the cancer has spread to other parts of the body that is, stage 2B or 3. Lawrence Einhorn at Indiana University. Lymph node surgery may also be performed after chemotherapy to remove masses left behind stage 2B or more advanced , particularly in the cases of large nonseminomas.
Seminoma[ edit ] As an adjuvant treatment, use of chemotherapy as an alternative to radiation therapy in the treatment of seminoma is increasing, because radiation therapy appears to have more significant long-term side effects for example, internal scarring, increased risks of secondary malignancies, etc. Two doses, or occasionally a single dose of carboplatin , typically delivered three weeks apart, is proving to be a successful adjuvant treatment, with recurrence rates in the same ranges as those of radiotherapy.
Since seminoma can recur decades after the primary tumor is removed, patients receiving adjuvant chemotherapy should remain vigilant and not assume they are cured 5 years after treatment.
This approach ensures that chemotherapy and or radiotherapy is only given to the patients that need it. For both non-seminomas and seminomas, surveillance tests generally include physical examination, blood tests for tumor markers, chest x-rays and CT scanning. However, the requirements of a surveillance program differ according to the type of disease since, for seminoma patients, relapses can occur later and blood tests are not as good at indicating relapse.
For patients with renal impairment, dose adjustments are often based on pharmacokinetic data at the time of clinical trials. Many trials of dose adjustment tailored to renal function have used Ccr as calculated from the Cockcroft-Gault equation.

In , the United States Food and Drug Administration FDA published guidance for pharmacokinetics research in patients with impaired renal function [ 9 ]. Although this guideline is not related to drug dose adjustments, it shows that eGFR may be used frequently to assess renal function in clinical trials in Japan going forward.
The objectives of this draft are to examine existing findings on renal function assessment in the administration of anticancer drugs, and to determine the usefulness and limitations of this assessment in real-world settings. Commentary Renal excretion of drugs occurs by glomerular filtration and tubular excretion; however, because there is no simple method for quantitatively assessing the drug excretion function of renal tubules, drug dose adjustments are typically based on GFR.
Therefore, GFR has been established as the reference for adjusting doses of anticancer drugs. Measurement of GFR requires measurement of the clearance of a substance that is completely filtered by glomeruli, does not bind to proteins, is not metabolized in the body, and is not secreted or reabsorbed by renal tubules.
In Japan, the gold standard is inulin clearance; other countries, however, measure clearance of substances such as 51Cr-EDTA, I sodium iothalamate, or iohexol. The use of these methods in clinical settings is constrained by the need for administration of reagents and urine collection, as well as a certain length of time before results are reported.
These constraints have resulted in the development of equations for estimating GFR and Cr based on serum Cr levels. Conventionally, drug doses have generally been adjusted using Ccr as estimated with the Cockcroft-Gault equation.

However, because Ccr estimates are higher than GFR values, several different equations have been developed for the accurate estimation of GFR; these equations are now also used to adjust drug doses [ 13 ]. Most equations for calculating eGFR and Ccr were developed for use in healthy individuals and CKD patients; few such equations are intended for use in cancer patients.
Although the Wright formula [ 5 ], the Martin formula [ 6 ], and the Jelliffe equation [ 7 ] are intended for the estimation of GFR in cancer patients, no method has been developed for estimating GFR specifically in Japanese cancer patients. Results are inconsistent among studies that have examined the validities of various predictive formulas for cancer patients; this lack of consistency is assumed to potentially lead to the overestimation and underestimation of true GFR within a certain range.
Overestimation of GFR can result in excessive doses of anticancer drugs and increased risk of side effects, while underestimation of GFR can lead to insufficient doses of anticancer drugs and a consequent attenuation of anticancer action. Research is also necessary to assess the usefulness of equations for estimating GFR based on serum cystatin C rather than serum Cr. Most studies compare eGFR to the gold standard of actual GFR; no studies have examined therapeutic effects and side effects resulting from administration of anticancer drugs based on eGFR.
However, in the adjustment of doses based on data from clinical trials, it is safe to use the same renal function assessment methods and predictive equations. No matter which predictive equation is used, for patients with a markedly abnormal condition whose renal function necessitates anticancer drug dose adjustment or who are borderline for such adjustment, rather than using eGFR based on serum Cr value, it is safer to use a combination of other methods such as actual GFR based on urine collection Note 2 and GFR as estimated based on cystatin C.
Although actual GFR based on urine collection and inulin clearance is preferable, when these are difficult to implement, GFR can be approximated by multiplying Ccr enzymatic method by 0.
When performing dose adjustments in accordance with Ccr or GFR, the following point must be noted: when assessing Ccr and GFR, the decision of whether to correct for body surface area is related to the method of measuring serum Cr value using the Cockcroft-Gault equation.
Boundaries: When to Say Yes, How to Say No to Take Control of Your Life
The EMA Guideline on the evaluation of the pharmacokinetics of medicinal products in patients with decreased renal function also recommends that GFR be measured and recorded without correcting for body surface area [ 10 ].
Therefore, caution is necessary when applying these equations. Although some patients who undergo cancer drug therapy for urinary tract tumors possess only one kidney, eGFR reflects the aggregate function of both kidneys; therefore, eGFR can also be used for patients with only a single kidney. For serum Cr values determined with an enzymatic method, 0. See Note 2 for the formula for estimating body surface area.Opticron Hand Lens 23mm 10x Magnification4.
